Colorado quarterback Jordan Webb will miss the 2013 season after tearing a ligament in his right knee at spring practice.
Webb tore the ACL on a cut in a noncontact drill Tuesday. The school confirmed the injury Wednesday in a release.
Colorado said Webb, a fifth-year senior, will work with the compliance office to try to gain a sixth year of eligibility.
Webb arrived at Colorado last season after playing for Kansas, and was named the Buffs' starter. He threw eight TDs and eight interceptions as Colorado went 1-11, leading to the dismissal of coach Jon Embree.
Said new coach Mike MacIntyre: "He was doing well in practice, competing again for the starting job, and for this to happen and to lose him for the season is just a shame."
