Utah State quarterback Chuckie Keeton will miss the rest of the season with a knee injury sustained against BYU on Friday night, the Aggies announced on Saturday.
Keeton suffered a torn ACL and MCL in the first quarter of Utah State's 31-14 loss to BYU.
"Very unfortunate situation for both Chuckie and our team," said coach Matt Wells. "We've lost a great leader, great teammate and a very productive football player. I have all the confidence in the world in Chuckie, along with our doctors and staff that he will come back stronger than ever next season. As for the remainder of this season, we will regroup as a team and pick up the slack and continue to strive to compete for the Mountain West championship."
Keeton finished the 2013 season 136-of-196 passing for 1,388 yards, 18 touchdowns and two interceptions. He also rushed for 241 yards on 55 carries with two more touchdowns. He ranks first all-time at Utah State in completion percentage (.665), second in touchdown passes (56) and tied for second in completions (517). The loss of Keeton is a big one for Utah State; he accounted for 67 percent of the Aggies' total offense this season prior to Friday night. It appears junior Craig Harrison is the likely successor to Keeton at quarterback for the rest of the year. Harrison filled in for Keeton in Friday's loss to the Cougars, finishing 18-of-41 for 185 yards and one touchdown.
