Holmes not part of drills at NFL combine

Former USC center Khaled Holmes was unable to take part in the on-field testing drills for offensive linemen on Saturday at the NFL combine.

Holmes suffered a strained pec during the bench press portion of the combine on Friday when he put up 13 reps before being forced to withdraw due to the injury.

The timing of this latest injury -- which forced him to sit out the 40-yard dash and other drills -- is unfortunate for Holmes after being forced to withdraw from the Senior Bowl due to an undisclosed injury. Holmes had battled through an ankle injury in 2012 and neck/stinger issues earlier in his career at USC so there are questions about his durability from the NFL scouts.

There will still be a chance for Holmes to make a strong impression at the USC pro day on March 27, which figures to draw a large continent of coaches and personnel evaluators.

Holmes is ranked as the No. 4 center prospect by Mel Kiper from ESPN.
