Has Erik Karlsson’s lingering groin injury resurfaced?

It plagued him for most of the second half of the season.

A good chunk of January, a good chunk of February, and the entirety of March, to be exact.

And now Erik Karlsson‘s Game 5 status is up in the air after he appeared to aggravate a lingering groin injury, one Karlsson said had only progressed in the right direction throughout the Stanley Cup Playoffs after Game 1 of the Western Conference Final.

“I don’t have anything for you there,” said Sharks head coach Peter DeBoer when quizzed on Karlsson’s health following a 2-1 loss to the St. Louis Blues that evened the best-of-seven series 2-2 on Friday.

DeBoer quickly swept that question under the rug.

As did Brent Burns, who just said, “He’s doing good” followed by a “How’re you doing?” when a reporter probed Burns about his teammate.

You may not have noticed it, initially at least.

Normally guys who play 24:33 in a game don’t miss significant stretches. But from the 10:36 mark to 18:05 of the third period, Karlsson didn’t see the ice. With the Sharks trailing 2-1 at the time, you’d expect one of the game’s best offensive defensemen to be on the ice. Instead, Karlsson was grimacing in pain, coming out during commercial breaks to test whatever was ailing him.

Somehow, he played the final 1:55 of the game — nearly two minutes of madness where the Sharks tried, ultimately in vain, to find an equalizer. Karlsson bit down hard on his mouthpiece and bore the pain, but you could see its effects.

PHT’s James O’Brien wrote on Karlsson’s playoffs prior to Friday’s game.

Karlsson limped into the playoffs and said himself that he could barely move in Round 1 against the Vegas Golden Knights.

Still, and as James pointed out in his story, it’s been hard to notice with two goals and 14 assists in 18 postseason games. Karlsson has played big minutes and produced at nearly a point-per-game pace in the playoffs, essentially everything the Sharks envisioned he would do when they brought him in last summer.

What they didn’t want was a nagging injury that force Karlsson to missed 29 games during the regular season and now, perhaps, some at a critical juncture for a team that’s hoping they’ve finally put it all together this year.

Maybe it’s nothing. But those painful faces that Karlsson wore in Game 4 weren’t exactly inspiring confidence in the “maybe it’s nothing” part.

If Karlsson can’t play, it’s only going to mean more minutes for guys like Burns, who is already averaging nearly 29 minutes a night. Karlsson has played an instrumental role in these playoffs for the Sharks.

A loss, even for a game, would be a massive blow in what’s now a best-of-three series.
