Alabama running back Najee Harris wasn’t included on Nick Saban’s injury report on Saturday, but there is growing concern that the sophomore is dealing with an injury.

After not participating during the open period of practice on Monday, Harris was at camp on Tuesday but had his leg on a scooter wheeling by reporters, according to Ben Jones of The Tuscaloosa News.

Rumors have circulated that Harris may have sustained an injury during Saturday’s scrimmage, but nothing appears to be certain at this point. The running back isn’t scheduled to meet with the media again until Thursday.

Last season as a freshman, Harris played in all 14 games for Alabama, rushing for 370 yards and three touchdowns. He was poised to have an even larger role in the Crimson TIde’s offense this year.

If Harris’ injury is legitimate, it is unclear how much time he would miss, or if he would be ready to play in the Tide’s season opener against Louisville on Sept. 1.
