The Pittsburgh Penguins placed forward Kevin Hayes on injured reserve Monday with an upper-body injury.
The move is retroactive to his last appearance on Nov. 5, meaning he could return Wednesday against Detroit.
Coach Mike Sullivan told reporters Sunday, however, that Hayes is considered week-to-week.
Hayes, 32, has three goals and one assist through 14 games in his first season with the Penguins.
He has 419 points (171 goals, 248 assists) in 727 games with five teams since being drafted in the first round in 2010.
