Colorado State Rams quarterback M.J. McPeek will again be the Rams' backup quarterback.

The senior was brought in mid-game Sept. 29 against Air Force when starter Garrett Grayson broke his clavicle, and McPeek made it through the rest of that game, a full game as a starter game and another two quarters before being knocked out with an injury to his non-throwing shoulder Saturday against San Diego State.

Christopher Dempsey of the Denver Post reported that Colorado State coach Jim McElwain is hoping to have McPeek ready to be the backup for the Rams' next game, Oct. 27 against Hawaii.

"We're hopeful, as we are with all of these guys, that we can get him back sooner than later," McElwain said. "It is a non-throwing shoulder, which is good. This week will be heavy rehab, and hopefully we can get him in a backup role, is what we're trying to look for as we move forward."

McPeek is 43 of 76 for 533 yards, four touchdowns and three interceptions this season.

Grayson, a sophomore who leads the team with 885 passing yards and seven touchdowns, has started throwing, Dempsey reported, but McElwain and the Rams' training staff are proceeding with extreme caution.
