BOSTON -- Boston Bruins center David Krejci is day to day with a lower-body injury and his availability is in question for Game 6 of the Eastern Conference First Round against the Ottawa Senators at TD Garden on Sunday (3 p.m. ET, NBC, SN, TVA Sports).
The Bruins defeated the Senators 3-2 in the second overtime in Game 5 on Friday but trail the best-of-7 series 3-2.
"[Krejci's] getting treatment this morning," Bruins coach Bruce Cassidy said Saturday. "[He] will be looked at further, but obviously he'll be a day-to-day situation right now. That's the best I've got going forward. We'll have a clearer idea [Sunday] when we get to the rink if he'll be able to play or not."
Krejci, who missed the first two games of the series with an upper-body injury, played 6:21 in the first period of Game 5 before he was injured on a hit by Ottawa defenseman Chris Wideman and did not return.

Cassidy has several options to replace Krejci if he can't play and said he could insert a wing and move someone to center.
Center Ryan Spooner played the first four games of the series before he was scratched for Game 5, replaced by Sean Kuraly, who scored two goals, including in the second overtime. Left wing Matt Beleskey has played two games in the series. Center Jakob Forsbacka Karlsson made his NHL debut in Boston's regular-season finale but has not played in this series.
"We've put a lot of thought into it, but we're not 100 percent sure yet who that player will be," Cassidy said. "We have our choices and you know who they are. We'll look at every one of them and if there's anybody [Friday] night that we feel [deserves to come out], we could put one or two guys in. But those decisions will be made [Sunday]."
Defenseman Torey Krug (lower body) has resumed skating but is far from making his first appearance in this series. Defensemen Brandon Carlo (upper body) and Adam McQuaid (upper body) remained off the ice.
