TORONTO — Their team defense in need of some tightening after a 4-2 loss Monday night, the Bruins gave rookie blue liner Matt Grzelcyk the green light to return to the lineup Thursday night in Game 4 of their opening-round playoff series vs. the Maple Leafs.
Grzelcyk, a solid contributor over the second half of the regular season, played in Games 1-2, both of them convincing Boston victories, then moved to the sidelines with a minor injury for Game 3.
“He should be good to go,’’ said coach Bruce Cassidy, whose squad had an optional workout Thursday morning at Air Canada Centre.
