Krejci leaves Game 5 after knee-on-knee with Wideman

The Boston Bruins took a hit at the center position Friday night.

David Krejci left Friday's game after a knee-on-knee collision with Ottawa Senators defenseman Chris Wideman.

The Bruins later ruled out Krejci's return. He was playing in his third postseason game in which he's been held pointless.

The Bruins are down three games to one.
