Matt Grzelcyk finally has cleared the NHL’s concussion protocol. The question now is whether he’ll actually play against the St. Louis Blues in Game 7 of the Stanley Cup Final.

The Boston Bruins defenseman was cleared to return to game action Wednesday and likely will replace Connor Clifton in the lineup, according to head coach Bruce Cassidy. Grzelcyk has been out since suffering a head injury in Game 2.

The Boston University product officially is listed as a game-time decision.

Grzelcyk’s speed and ability to jump-start the rush could be a huge addition for the Bruins, who have struggled at times with the Blues’ tenacious forecheck.

Game 7 is scheduled to start at 8 p.m. ET at TD Garden.
