[UPDATE: Eichel has been traded to Vegas for a package that includes Alex Tuch and Peyton Krebs.]

Through the 2021 NHL Draft and early free-agent stages, the Sabres haven’t been able to get a Jack Eichel trade done. That doesn’t mean that things have been quiet between Eichel and the Sabres.

At first, Sabres GM Kevyn Adams insisted there was “no rush” on an Eichel trade. That talking point didn’t stick thanks to a surprising statement from Jack Eichel’s agents. Their comments made it clear that there’s still a tense debate between Eichel and the Sabres about what type of neck surgery he should undergo. (At least the Sabres and Eichel agree about a neck surgery being needed. So far?)

That no-rush part is in peril for an interesting reason. Eichel’s agents laid out a scenario where, if Eichel can undergo his preferred form of neck surgery, he might enjoy a swift recovery. Here’s the statement from Eichel’s agents, via Lance Lysowski of the Buffalo News:

Ultimately, though, the Sabres technically have the last say thanks to language in the CBA. So, the impasse remains, and the debate lingers. It’s unclear when there might be a resolution regarding a Jack Eichel trade, or an agreement from the Sabres about his neck surgery.

Amid all of this, most of us have been uncomfortable with a certain thought. What, exactly, is the debate between the Sabres and Eichel regarding this neck surgery choice?

Now we have some deeper insight … at least from Jack Eichel’s perspective. In an absolutely essential interview with Elliotte Friedman and Jeff Marek, Dr. Chad Prusmack laid out the argument, mainly from Eichel’s perspective (and his).

Dr. Prusmack confidently argues for Eichel’s preference: artificial disc replacement surgery. Meanwhile, the Sabres prefer anterior cervical discectomy and fusion (ACDF) surgery. (For the sake of ease and brevity, we’ll stick to “disc replacement” and “fusion” or ACDF in this post.)

If you want more insight into this situation, Prusmack provides it to Friedman and Marek. This post gathers some crucial quotes, claims, and details. Then we’ll wonder what it means for those who might want to make an Eichel trade.

Huge flashing disclaimer: Much like what Friedman and Marek note in that interview, these medical issues are above my pay grade. Consider this a big-picture view, mainly of Eichel’s side.

Eichel’s preference: disc replacement vs. Sabres’ preference: fusion

Here are two very basic explanations for how ACDF/fusion and disc replacement surgery are similar, and how they are broadly different.

  • In both cases, a disc is generally removed from the spine. Replacing that disc is what separates the two procedures. With fusion/ACDF, a surgeon places a graft between vertebrae. Over time, the bones fuse together as they heal. NHL players have undergone this type of neck surgery.
  • Then, you have artificial disc replacement, which Dr. Prusmack notes became available around 2000. In this case, it’s a lot like getting an artifical hip or knee. After the disc is removed, the artificial disc is put in its place.

Importantly, Dr. Prusmack insists that both fusion and disc replacement can be considered “phenomenal procedures.” He’s not totally dismissing the merit of the Sabres’ preferred procedure. That said, he strongly prefers disc replacement surgery, Eichel’s would-be choice.

The case for disc replacement

“If anyone says a fusion is better for someone in the long run, they are not telling the truth, or they don’t know the literature,” Dr. Prusmack told Friedman and Marek around the 27-minute mark.

According to Dr. Prusmack, about 25-percent of people who undergo fusion surgery will need to go under the knife again within 10 years. Meanwhile, Dr. Prusmack puts the rate for disc replacement between 4.5 and 5-percent.

Dr. Prusmack views disc replacement as something closer to “one-and-done,” while fusion carries the risk of “one surgery after another.”

Along with long-term implications, there could be short-term advantages. By Dr. Prusmack’s estimates, a player normally gets evaluated three months after fusion. If that goes well, the timetable to play could be anywhere from 6-9 months.

On the other hand, artificial disc replacement could mean getting back to skating by about six weeks, and possibly engaging in contact within about eight.

[Catch up on NHL trades that have already actually happened.]

There are even possible performance advantages. Dr. Prusmack argues that, with an artifical disc replacement, a player can maintain closer to the normal range of neck motion as before they underwent surgery. With fusion, he compared the addition to something as flexible as “bamboo.”

Dr. Prusmack’s goal: to make Jack Eichel “as close of an indentical twin” as what Eichel was before the surgery. Artifical disc replacement, ideally, would allow Eichel to remain at his elite level. With fusion, it’s possible there will be a disruption of his “neuromechanical coupling.”

That mobility argument has backing. Take, for instance, the Orthopedic Institute of Philadelphia noting “increased spine mobility”

Fascinating stuff. Overall, Dr. Prusmack makes a persuasive argument on “31 Thoughts.”

Limited view of Sabres’ side

At the moment, we know that the Sabres currently favor fusion for Jack Eichel’s neck surgery. There isn’t a ton of insight about the Sabres’ objections to disc replacement surgery.

The little we reportedly know is that:

  • There’s concern that an NHL player hasn’t undergone artifical disc replacement neck surgery yet.
  • Perhaps, that it’s a relatively new procedure, having been introduced around 2000. Meanwhile, fusion is far more established.

Is there more? Maybe the Sabres will shed more light on their preference for ACDF/fusion down the line.

For what it’s worth, Dr. Prusmack claims that disc replacement isn’t “experimental.” It merely hasn’t happened in the NHL yet (he’s claimed to have treated hockey players at other levels, along with athletes in different sports).

“It has a really, really good track record, we just don’t have a track record in the NHL,” Dr Prusmack said.

MMA/rugby comparisons

Dr. Prusmack claims that fusion might make sense for NFL players. NHL players may benefit from disc replacement like athletes who play rugby or engage in MMA. (While football contact can be “blunt, head-to-head,” rugby and MMA often create “whip-like” contact to the head. That might be more akin to what hockey players more generally experience.)

With that, there’s a testimonial from MMA fighter Chris Weidman.

Implications for Eichel trade value?

While there could certainly be more facets to this (especially in favor of fusion), it’s at least useful to get an idea of the sides in the Jack Eichel – Sabres neck surgery debate.

But how should would-be Jack Eichel trade suitors feel about all of this?

On the one hand, a swift recovery could be really nice. That’s especially true if a team traded for Jack Eichel under a win-now edict.

That said, it also underscores the risks involved.

What if disc replacement surgery turns post-surgery Jack Eichel into a weak clone, as if he became hockey’s answer to “Multiplicity?” If fusion ends up being the answer, what if he really does struggle to be anywhere near the player he was?

Eichel’s $10 million cap hit already is risky. It lasts for five more seasons, and a no-movement clause kicks in starting in 2022-23. The Sabres understandably want a big return for Eichel, yet that only makes a trade even scarier.

Especially if you’re a team that’s already uneasy about investing so much in a player who’s experienced so little team success. (I’d argue Eichel doesn’t deserve much blame there, but still.)

Ideally, this works out for everyone involved: Eichel, the Sabres, and whoever might trade for him. Getting that far might not be easy, though.

Maple Leafs’ Matthews out at least 3 weeks with knee injury

Toronto Maple Leafs center Auston Matthews will miss at least three weeks with a sprained knee.

The team announced the reigning MVP’s anticipated absence Friday, two days after Matthews was injured in Toronto’s victory against the New York Rangers.

Matthews is expected to miss at least six games and could be out for a few more. The timing of the injury coinciding with the NHL All-Star break and the Maple Leafs bye week prevents this from costing Matthews more time out of the lineup.

After being voted an All-Star by fans, Matthews is now out of the event scheduled for Feb. 3-4 in Sunrise, Florida. The league announced Aleskander Barkov from the host Florida Panthers will take Matthews’ place on the Atlantic Division All-Star roster.

Matthews, who won the Hart Trophy last season after leading the NHL with 60 goals, has 53 points in 47 games this season.

Caufield opted for surgery with Habs out of playoff race

MONTREAL — Montreal Canadiens winger Cole Caufield said Friday he wouldn’t be having season-ending surgery on his right shoulder if the team were in playoff contention.

But with the Canadiens near the bottom of the Eastern Conference standings, the 22-year-old Caufield said he decided to have the surgery to protect his long-term health. The procedure is scheduled to be performed by Dr. Peter Millett on Wednesday.

“I didn’t want to stop playing,” Caufield said. “I had a couple tests done to look at it more clearly but, in the end, like it could’ve been one more fall and it could have been even worse.”

Caufield, who leads the Canadiens with 26 goals in 46 games, had three different medical opinions on his shoulder before concluding that his season was over.

“I think they’ve seen a lot more than I have and they know the differences and what they like or don’t like about it,” he said about the medical opinions. “Long term, I think this is what’s best but for sure it was tough to sit out that game against Toronto on Saturday night.”

Caufield initially felt the injury in an awkward fall during Montreal’s 4-2 loss at Dallas on Dec. 23. He said his right shoulder popped, and he replaced it himself.

Caufield felt it again in the Habs’ 4-3 loss at Nashville on Jan. 12. The club announced on Jan. 21 that Caufield would miss the rest of the season.

Caufield is nearing the end of his three-year, entry-level contract and will be a restricted free agent this summer.

All-Star Matty Beniers to miss next 2 games for Kraken

SEATTLE — Seattle Kraken rookie All-Star Matty Beniers will miss the team’s final two games before the All-Star break after taking a big hit from Vancouver’s Tyler Myers earlier this week.

Seattle coach Dave Hakstol said after morning skate Friday that Beniers would not play Friday night against Calgary or Saturday against Columbus. Hakstol did not speculate on Beniers’ availability for next weekend’s All-Star Game in Florida.

The team has not specified what kind of injury Beniers sustained from the hit. He was barreled over by Myers away from the play early in the second period in Wednesday’s 6-1 victory over Vancouver. Myers was penalized for interference on the play. Beniers returned briefly for one shift later in the period but did not play in the third period.

Beniers is Seattle’s lone All-Star selection this season. He leads all rookies in goals (17) and points (36), and is fifth in total ice time for rookies.

Seattle also placed defenseman Justin Schultz on injured reserve and recalled forward Max McCormick from Coachella Valley of the AHL. Hakstol said Schultz is improving but there’s no timeline on his return.

VANCOUVER, British Columbia — Forward Andrei Kuzmenko signed a two-year contract extension with the Vancouver Canucks on Thursday.

The deal has an average annual value of $5.5 million.

The 26-year-old Kuzmenko has played in 47 games for the Canucks this season with 21 goals and 22 assists, four penalty minutes and a plus-4 defensive ranking.

Kuzmenko ranks second on the team in goals and power-play goals (nine) this season.

His 43 points are also tied for third on the team in overall scoring, while his 32 even-strength points (12 goals, 20 assists) are second on the Canucks.

Kuzmenko leads all Vancouver skaters in shooting rate (24.7%) and ranks third in the NHL in that category (minimum of 20 games).

He leads all first-year NHLers in almost every offensive category, including goals, assists, points, points per game (0.91), power-play goals, and power-play points.

He has also had 14 multi-point games so far this season (second most on the Canucks), highlighted by his first-career NHL hat trick and season-high four-point game against Anaheim on Nov. 3.

A native of Yakutsk, Russia, Kuzmenko spent his first eight professional seasons in the Kontinental Hockey League (KHL) with CSKA Moscow and SKA St. Petersburg, getting 200 points (85-115-200) in 315 regular-season games. He set career highs in goals (20), assists (33), and points (53) last season, ranking second in the league in scoring.

Kuzmenko has also represented his country on the international stage on multiple occasions, totaling 16 points (10-6-16) and six penalty minutes in 37 games played. He was originally signed by Vancouver to a one-year, entry-level contract on July 13, 2022.
