Theo 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, two people familiar with the procedure told the Free Press. They would not go on record because they are not authorized to talk about it publicly.
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.
Riddick's per game average of 16.2 fantasy points (PPR) was the 8th-highest at his position. With Ameer Abdullah also returning from injury, Riddick may not see as many carries, but he should continue to play a big role in the passing game. He averaged 5.3 catches per game last year.
