Senior nose tackle Jason Shirley will sit out the first two games of the football season, Fresno State coach Pat Hill announced this morning.

He did not disclose the reason for Shirley's suspension, but said it was for conduct detrimental to the team.

Shirley didn't practice with the team on the first day of practice August 6 because he missed a 6 a.m. conditioning test. Instead he was forced to push the sled and perform other solitary conditioning exercises that day.

Hill said Shirley hasn't missed a practice this August and that this has been Shirley's best training camp at Fresno State.

Charles Tolbert is at the head of the depth chart the Bulldogs released today. Hill mentioned Mark Roberts and Cornell Banks as players who may receive more playing time in Shirley's absence.

Shirley started seven games last season and played in all 12, tallying 20 tackles and two sacks.
