NASHVILLE, Tenn. (AP) -Nashville forward Martin Erat will miss up to four weeks with a sprained right knee, after colliding with teammate Jason Arnott.
Erat and Arnott slammed into each other in the third period of Tuesday's 5-2 loss to Detroit and had to be helped from the ice. The Predators are scheduled to play the Red Wings on Wednesday night.
The 25-year-old Czech had been playing on the Predators' top line with Paul Kariya, and he scored a goal Tuesday to increase his career-high in points to 57.
Erat has played in 68 of Nashville's 71 games this season and now joins an injury list that includes Peter Forsberg (upper body injury), Steve Sullivan (back), center Scott Nichol (broken thumb) and Scott Hartnell (broken foot).
