Senators defenceman Jakob Chychrun will be sidelined multiple weeks due to a lower-body injury, head coach D.J. Smith told TSN 1200 in Ottawa on Saturday.
Smith also announced forward Ridly Greig will miss the remainder of the regular season due to a sternum injury. Both players were injured during the Senators' 7-2 victory over the Tampa Bay Lightning on Thursday.
Chychrun did not participate in practice Friday, and Smith told reporters that the defenceman "tugged something there a little bit, we'll see how he reacts to treatment here." The Senators (35-32-5) have 10 games remaining in the regular season, which ends April 13 at Buffalo.
Ottawa is five points out of the second wild-card spot in the Eastern Conference entering play Saturday. Chychrun, who turns 25 on Friday, has recorded five points in 12 games with the Senators since being acquired from the Arizona Coyotes on March 1.
