Oklahoma State redshirt freshman running back Kye Staley sustained a knee injury Saturday in the Cowboys' scrimmage that likely will sideline him for the rest of the season.
Several Oklahoma newspapers reported that Staley possibly sustained a torn anterior cruciate ligament in his right knee.
Coach Mike Gundy had been pleased with Staley's development in camp. He had gone from 241 pounds to 212 and was expected to contend for playing time in the crowded Oklahoma State backfield.
"Kye has come a long way," Gundy said last week. "He's going to make some plays for us when he has the opportunity."
But Staley was counted on as perhaps the Cowboys' top future prospect at the position and would have learned much playing behind the experienced trio.
His injury could mean that freshman Jeremy Smith and redshirt freshman Travis Miller have a chance at playing time.
