The junior sustained the injury in the first quarter of the Aggies’ 31-14 loss against visiting BYU on Friday.
“Very unfortunate situation for both Chuckie and our team,” Utah State coach Matt Wells said over the weekend. “We’ve lost a great leader, great teammate and a very productive football player.”
Keeton was 4 of 10 for 26 yards, one touchdown and an interception before leaving the game. He also rushed three times for 17 yards.
In six games this season, the 6-foot-2, 200-pound Houston (Cypress Creek High School) native completed 135 of 196 attempts for 1,388 yards, 18 touchdowns, and two interceptions. On the ground, he rushed 55 times for 241 yards, and two scores.
Keeton was a Heisman Trophy dark-horse candidate entering the season, and, if he can return to full health, he may enter as one his senior year.
“I have all the confidence in the world for Chuckie, along with our doctors and staff that he will come back stronger than ever next season,” Wells said. “As for the rest 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’s 56 career passing touchdowns ranks second all-time in school history.
Junior quarterback Craig Harrison replaced the injured Keeton against BYU and will likely be the starter the remainder of the season. In relief of Keeton, Harrison was 18 of 41 for 185 yards and a TD.
The Utah State offense will likely see a dip in production until the Grantsville, Utah native can get comfortable facing the tough defenses in the Mountain West.
Utah State (3-3, 2-0 Mountain West) hosts Boise State at 8 p.m. Saturday at Romney Stadium in Logan. CBS Sports Network is tabbed with the broadcast.
