Junior running back Jermie Calhoun, who tore his ACL last season in a game against Colorado, was back in action at the Sooners' Thursday practice.
Calhoun isn't expected to play much of a role this season for the Sooners, with a few players ahead of him on the depth chart. He only had 11 carries last year and Oklahoma will probably take things slow with Calhoun coming off the ACL tear.
