This is from UCLA:

Pat Cowan’s MRI shows damage to his left ACL and his medial meniscus. He will be reexamined when the swelling decreases.
Ben Olson’s X-rayshows a fracture in his right 5th metatarsal. It is possible that he may have a screw put in the bone. He will be sidelined 6-8 weeks.

I will talking to coach Rick Neuheisel on a conference call soon about this stuff.
