Late on Friday night, Kentucky officials confirmed various reports that sophomore running back Josh Clemons injured his leg in workouts earlier in the day.
Clemons, who sat out last season nursing a surgically repaired knee, will have an MRI and coaches expect to know more about the extent of the leg injury on Monday, spokesman Tony Neely said Friday night.
Neely said he did not know the exact nature of the injury, nor which leg Clemons had hurt, only saying that Coach Mark Stoops confirmed there was an injury.
Many believed that the sophomore running back, who showed signs of being an elite level player early his freshman season before tearing his meniscus at South Carolina, had turned a corner and his knee was back to full strength.
He drew praise from offensive coordinator Neal Brown after one of UK's spring scrimmages.
When Clemons was asked about the knee this spring, he said he felt close to 100 percent again: "It's feeling good. It's the best it's felt."
If Clemons is sidelined again, a spot where UK was thought to have considerable depth will be much less so.
The Cats return seniors Jonathan George and Raymond Sanders as well as sophomore Dyshawn Mobley. Highly touted freshman Jojo Kemp also is expected to be an impact player.
