Johnny Boychuk felt better after skating on Saturday morning, but not well enough to play. Boychuk missed his second straight game with a lower-body injury, suffered when he blocked a shot late in the Islanders’ loss in Tampa on Tuesday. “It hurt but that was the second-to-last shift of that game, then we were off the next day,” he said. “I went out for the morning skate [in Pittsburgh on Thursday] and you just don’t know how it’s going to feel. I’m getting better and it stinks not to play against my old team, but you have to be smart or it could end up being a few weeks instead of a few days.” Boychuk played for the Bruins from 2008-14. If he’s able to practice on Sunday, there’s a chance he’ll be able to play Monday against the Capitals in Barclays Center.
