ALLEN PARK — Lions’ running back Jahvid Best (concussion) did not practice today (Tuesday). Best has missed the last two games and his availability for this week became suspect when the Lions brought back running back Kevin Smith on Monday.

Smith, wearing No. 30, was practicing on Tuesday along with veteran guard Leonard Davis (No. 75) who was also signed to a one-year deal on Monday.

All others were present and accounted for during Tuesday’s extra practice following the bye week.

The Lions play at Chicago on Sunday at 4:15 p.m.

In a practice squad move, the Lions signed wide receiver Terrance Toliver and cut tackle Casey Bender.
