The Facts: Riddick, who missed the final month of the regular season last year, had surgery on both of his wrists, which prompted his season-ending trip to injured reserve.
Diehards Line:The Lions did not announce Riddick's surgery at the time he went on IR, and Riddick declined comment on his injury after the season, while he was wearing a cast on his left wrist. Riddick is expected to be a full participant in organized team activities later this spring, but his injury is another consideration for a Lions team looking at possibly upgrading its backfield this off-season. Ameer Abdullah played in parts of two games last year before undergoing season-ending foot surgery – he also underwent surgery to repair a torn labrum in his shoulder after his rookie season of 2015 – and Riddick missed seven games total last year, including the playoffs, with wrist and ankle injuries. The Lions finished 30th in the NFL in rushing last season, and GM Bob Quinn has been open about his desire to fix the running game this spring.
