Before his knee gave out in October 1984, Detroit Lions running back Billy Sims was in the midst of an outstanding season. Now, after 18 months of rehabilitation, Sims said he is ready to pick up where he left off.

Sims, the leading rusher in the history of the Lions, spent last season on the sidelines after aggravating the injury during a preseason workout.
