Ronnie Clark knew right away when he felt that familiar and painful pop.
As he laid on the field clutching his lower leg, Alabama head coach Nick Saban ran over and asked, "What's wrong?"
"I think I tore my Achilles," Clark told him. "It felt just like it did last time."
Working with the punt team, the former four-star recruit from Calera had taken off running. Then, pop.
After tearing his left Achilles tendon as a freshman in 2014, Clark had just torn the right one during the final period of the Crimson Tide's final 2016 spring practice.
