Theo Riddick's injury scare appears to be much ado about nothing. In his third game as the Lions' No. 1 tailback, Riddick was bounced in the fourth quarter after sustaining a wrist injury against Chicago. That sparked concern about his health because he's had some longstanding issue with the wrists, and underwent surgery on both of them last offseason. But he was back on the practice field when Detroit resumed work Wednesday, and he's expected to play Sunday in Cincinnati.
