ALLEN PARK, Mich. -- The Detroit Lions practiced on Christmas Day with nine players out, including wide receiver Calvin Johnson (knee) and running back Joique Bell (knee).
Detroit coach Jim Schwartz said the Lions might not know about Johnson's availability for the season finale against the Minnesota Vikings until Sunday.
Joining them were cornerback Bill Bentley (concussion), tight end Dorin Dickerson (concussion), linebacker DeAndre Levy (foot), safeties John Wendling (ankle) and Louis Delmas (knee) and tackle LaAdrian Waddle (ankle).
Schwartz said neither Bentley nor Dickerson had been cleared from concussion protocol after both suffered them Sunday against New York. Bentley, though, has progressed more than Dickerson.
Cornerbacks Chris Houston (toe) and Darius Slay (knee), along with defensive end Israel Idonije (neck) were limited for the Lions. Cornerback Rashean Mathis, who had the flu last week, practiced in full.
