Lions' Theo Riddick: Limited Wednesday

Riddick (ankle) was limited at Wednesday's practice.

Analysis:

Ankle injuries have kept the Lions' top two running backs (Riddick and Dwayne Washington) on the sideline for two and three games, respectively. Both returned to practice Wednesday, but unlike Washington, Riddick was unable to handle every drill. Their level of participation this week will likely determine who among the pair receives more work Sunday at Houston.
