STILLWATER, Okla. -- Nathan Peterson, the leader in sacks for No. 22 Oklahoma State, will miss the rest of the season after suffering a knee injury against Texas A&M, according to published reports.

An MRI exam showed the freshman tore his anterior cruciate ligament and will need surgery to repair the damage, the Tulsa World and The Oklahoman reported Wednesday, citing anonymous sources.

Cowboys coach Les Miles would not comment on Peterson's injury after practice Tuesday. On Monday morning, Miles said he had gotten good news but the MRI was Monday afternoon.

Peterson leads Oklahoma State with four sacks and six tackles behind the line of scrimmage. Other Cowboys linemen have just two sacks combined.

Peterson injured his knee in the second half of the Cowboys' 36-20 loss Saturday night to Texas A&M. He left the field on crutches and has not practiced since.

Peterson is expected to undergo surgery later this month and likely will not return to contact football until August 2005.

The Cowboys also likely will be without cornerback and punt returner Darrent Williams when they play Missouri Saturday. Williams has a fractured forearm that is now in a protective wrap.
