Bruins coach Jim Mora offered details on Rosen's injury for the first time Monday, having previously referred to it only as an upper-body injury after Rosen landed hard on his throwing shoulder in the fourth quarter of a 23-20 loss at Arizona State. Fafaul has thrown for 722 yards and eight touchdowns against six interceptions, setting school single-game records for pass attempts and completions in the 52-45 loss to the Utes. Mora also disclosed that running back Soso Jamabo is dealing with shoulder and ankle injuries, while Nate Starks has tendinitis in his knee.
