Detroit Lions RB Theo Riddick (wrist) underwent surgery on both of his wrists after the season, according to sources.

Footballguys View: Riddick is expected to be a full participant in organized team activities later this spring. The Lions should select a RB at some point in the 2017 NFL draft, and that player should be more of a full-time player. Riddick should continue as a fine receiving threat and change-of-pace back for the Lions.
