Horton suffered the injury during Sunday’s game against Philadelphia, when he took this shot from Flyers forward Tom Sestito during the second period (FF to 0:23 mark):
Horton was held out of the third period, overtime and shootout. Bruins coach Claude Julien said it was a “blindside hit” but didn’t speculate on the severity of the injury. That was left to Chiarelli.
“I don’t have an official update other than I think it’s a ‘mild concussion’ from what I saw and heard last night – and talking to him today,” he told CSNNE. “These things are day-to-day so I’d say he’s day-to-day.
“He’s in that gray area between taking the impact testing and see how it is the next day and the following day. Then you make a determination. He’s in that gray area right now.”
Horton has a history of head injuries dating back to the concussion suffered at the hands of Vancouver’s Aaron Rome during last June’s Stanley Cup Finals. That cost him the final four games of the series and a portion of his offseason skating routine, perhaps contributing to his slow start to this season.

“He’s been having the same problem here for a bit,” Mike Babcock told media members on Sunday. “He doesn’t seem to be getting the power back that they thought, so we’re just trying to monitor it the best we can.”
Leafs Nation points out that Lupul has missed about one-third of Toronto’s contests since suffering a separated shoulder in April 2012.
At 32, there’s still time for Lupul to fight through this, although injuries generally accumulate with age.
