“It feels pretty good working out,” Spence said. When Spence does take the field, it will be for the first time since suffering a left knee injury during last year’s last preseason game. The Tribune-Review is reporting that Spence is going to start back on the practice field, and that time for him to be back is next week. After surgery, 14 months of rehab, a spot on injured reserve and a stint on the physically-unable-to-perform list, Spence is ready to see if he still can be a professional football player.

Peroneal nerve injuries occur when multiple ligaments are torn and the leg stretches the outside of the knee, compromising the nerve that runs down the leg that controls the upward movement of the foot and toes.
