The Ottawa Senators placed forwards Matt Duchene and Bobby Ryan on injured reserve, the team announced Saturday. Duchene is considered week to week with a groin injury, while Ryan is out indefinitely with a concussion.

Duchene had been on pace for a career year, currently leading the Senators with 34 points in 29 games. Colin White and Chris Tierney will likely see increased roles while Ottawa's top center is sidelined.

Ryan has battled injuries throughout his time in the nation's capital, missing 20 games in each of the past two years. The injuries have hindered his production, as he hasn't surpassed 35 points since 2015-16. He was on track for a bounce-back campaign this season, registering 18 points in 29 games.

The Senators are last in the Atlantic Division with a 12-14-3 record.
