Avs' Mueller sidelined with concussion

A concussion is expected to keep Colorado Avalanche newcomer Peter Mueller sidelined for the final week of the regular season.

Mueller, who has a team-best nine goals since the Avs acquired him in a trade with Phoenix on March 3, was injured in Colorado's 5-4 win over San Jose in overtime Sunday night. After scoring two goals, Mueller crashed into the boards following a blind-side hit from former Avs defenseman Rob Blake .

The team said Tuesday there is no timetable for Mueller's return.

After scoring just four goals for the Coyotes , Mueller has 20 points in 15 games for the Avalanche , who are clinging to the eighth and final playoff spot in the Western Conference.
