BOULDER, Colo. -- Colorado Buffaloes sophomore quarterback Tyler Hansen broke his right thumb on his throwing hand in the Buffaloes' annual spring game Saturday.
Hansen was injured when he slammed his thumb into the helmet of defensive end Marquez Herrod in the third quarter when he was attempting a pass to fullback Jake Behrens in the flat.
Team spokesman David Plati said Hansen was scheduled for surgery at Boulder Community Hospital and is expected to be out until mid-June.
Hansen split snaps last season with junior quarterback Cody Hawkins.
"At first I figured I just jammed it, but then we figured it out later when they X-rayed it," said Hansen.
Hansen stayed in the game but said he had trouble taking the snaps and after one more pass, he just kept handing off to running backs.
"I came to the sideline and it was killing me and I got it looked at by the medical staff. They taped it up and I thought it was all right and I got the ball and said, 'No, I can't go,'" Hansen said.
Hawkins is now the only healthy quarterback on the Buffaloes' roster.
