Oklahoma State receiver Tylan Wallace, a Biletnikoff Award finalist in 2018, suffered a torn ACL in practice Wednesday and will miss the rest of the season, sources confirmed to ESPN on Friday.
An MRI on Thursday confirmed the injury, and it's unclear when Wallace will undergo surgery.
The Oklahoman first reported the diagnosis of his injury on Friday.
An OSU athletics department spokesman declined to confirm Wallace's injury because of team policy.
Wallace, a junior from Fort Worth, Texas, led the Cowboys with 53 catches for 903 yards with 8 touchdowns this season.
