Though coach Bruce Cassidy said it was a game-time decision for the defenseman, he also said, "It looks like he will go in."
Grzelcyk missed the past four games because of a concussion sustained in Game 2 on May 29. Blues forward Oskar Sundqvist was suspended one game for boarding by the NHL Department of Player Safety for the hit that knocked Grzelcyk out of the lineup and sent the 25-year-old into the NHL concussion protocol.
"I felt good," Grzelcyk said, of the morning skate on Wednesday. "Obviously really excited to get back in there hopefully. It's been tough watching when you get to this stage, but just trying to stay positive, cheering my teammates, and hopefully get out there tonight and have a good impact."
It had appeared that there was a chance Grzelcyk, who grew up in the shadow of TD Garden, where his father has worked on the Bull Gang -- the changeover crew at the arena -- for decades, could return as early as Game 5, but he was not medically cleared at that point, which wasn't easy for him.
"As a competitor, you want to be out there as quick as possible," he said. "I tried my best to get out there as soon as I could. I think they felt that I probably wasn't 100 percent, even up until maybe a couple of days ago**
