LEXINGTON — Kentucky running back CoShik Williams is out for the season with a hip injury.

An MRI revealed a torn labrum that will require surgery for the fifth-year senior, who has missed three of the past four games. Williams had a team-high 62 yards on 10 attempts against Louisville.

Wildcats coach Joker Phillips said Wednesday that he feels” heartbroken for him because the guy has worked so hard.”

Williams, who came to Kentucky as a walk-on, played in 25 games as a Wildcat, including seven starts. He rushed for 738 yards, averaging 4.3 per carry, with seven touchdowns. He had a career-high 148 yards last season in the win over Jacksonville State, along with 111 yards and two touchdowns in the victory over Ole Miss. He also scored what proved to the game-winning touchdown in the historic triumph over Tennessee.

As a sophomore, his top game came in the win over Charleston Southern, when he ran for 95 yards and a career-best three TDs.

“Everybody knows his story. The guy came here as a non-scholarship guy and worked his tail off to be a starter and is now out for the rest of the season,” Phillips said. “The reason why he was the starter is because the starter was already out in Josh Clemons. The next guy has to be up.”

Juniors Jonathan George and Raymond Sanders, and freshman Dyshawn Mobley will share carries for Kentucky (1-4, 0-2 Southeastern Conference) in Saturday’s game against No. 20 Mississippi State (4-0, 1-0).
