Buffalo Bills starting QB J.P. Losman did not practice on Tuesday and could miss this week's game against the Denver Broncos due to an injured right shoulder. Bills' head coach Mike Mularkey said that Losman will underdo an MRI.

"We'll make a decision (Wednesday)," Mularkey said.

Losman is currently listed as questionable on the team's injury report. Kelly Holcomb, who started five games this year and seemed to be in snyc with the offense, will start if Losman is unable to play.

Losman was injured early in the first quarter against the New England Patriots last Sunday. He started the game with a very poor completion percentage. He finished the game completing 10 of 27 passes for 181 yards and three interceptions.

The Bills will see the return of WR Eric Moulds this week, who was suspended for their game against the Patriots.
