The Boston Bruins will be without defenseman Torey Krug for at least Sunday's Game 5 of their series against the Tampa Bay Lightning due to a lower-body injury, head coach Bruce Cassidy confirmed Saturday.

Krug suffered an apparent ankle injury during Game 4, and Cassidy added that the initial prognosis isn't all that encouraging.

"He's still getting evaluated, but doesn’t look good that it will be short term," Cassidy said.

Krug is averaging just over 20 minutes of ice time for the Bruins this postseason, and ranks fourth on the team with 12 points in 11 games (three goals, nine assists).

Cassidy added that Nick Holden will enter the lineup to play alongside Adam McQuaid on Sunday.
