Alabama redshirt sophomore running back Ronnie Clark suffered a torn Achilles tendon in practice Thursday, sources told AL.com.

This is the second Achilles injury for Clark since arriving at Alabama.

The former Calera High School star tore the other Achilles tendon as a freshman in 2014.

Clark was working as the No. 3 running back behind Bo Scarbrough and Damien Harris this spring.

A former four-star recruit, Clark spent time at both safety and running back as a freshman, but has focused on running back full-time since returning from the first Achilles injury.

Clark ran for 20 yards on five carries as a redshirt freshman last year.

He rushed for 31 yards on seven carries during the Tide's second spring scrimmage on Saturday, a solid average of 4.4 yards per carry.
