After a 2-1 loss to the Pittsburgh Penguins yesterday, perhaps the best sign of the day for the Bruins came when David Krejci walked out of the locker room under his own power, though with a slight limp.

Just how positive a development that is remains to be seen, but Krejci looked a whole lot better than he did less than an hour earlier. With 5:14 remaining in the game at Consol Energy Center, Krejci was trying to screen Pittsburgh goalie Tomas Vokoun when he took the full brunt of a booming Johnny Boychuk slap shot off his right knee, then crumpled to the ice in pain. He had to be helped off the ice and wasn’t putting any weight on the leg.

When he left the rink, there were no visible signs of a brace, though he could have had the knee wrapped up under his pant leg.

Krejci did not speak to reporters and coach Claude Julien did not have an update. The center apparently traveled with the team to Winnipeg, where the B’s play tomorrow night.

After the game, Boychuk seemed shaken up at the possibility of injuring his teammate.

“I just tried to rip it and it hit him. I don’t know where it hit him, but I hope he’s OK. I haven’t seen him yet,” Boychuk said. “It was a good pass by (Zdeno Chara) and I had the whole lane to walk down, lots of time, and I tried to put everything on it and unfortunately I hit Krech.”

Knowing how hard Boychuk fires the puck, Krejci’s teammates could only hope for the best.
