Lions' James Houston: Won't be activated ahead of Week 18

Houston (ankle) has been ruled out for Sunday's game against the Vikings.

Houston was designated to return from injured reserve Dec. 28, but he'll miss his second straight game since then. The linebacker was able to log a trio of limited practice sessions during Week 18 prep, so it seems that he's making progress toward a return. The second-year linebacker may be able to play in Detroit's wild-card matchup next weekend.
