ALLEN PARK — Don’t expect to see Lions running back Jahvid Best in Thursday’s big tilt against the undefeated Packers.

Best did not practice today (Tuesday). He has missed the last four games with a concussion.

Coach Jim Schwartz is unlikely to announce who will start at running back, but expect to see Kevin Smith get the nod. In his second game back with the Lions on Sunday he carried 16 times for 140 yards and four catches for 61 yards. Maurice Morris, who had seven carries for 29 yards on Sunday, has been the starter with Best out.

Also missing from practice were WR Calvin Johnson (ankle), DE Lawrence Jackson (thigh), DT Corey Williams (calf) and P Ryan Donahue (quad).
