ALLEN PARK, Mich. -- Outside linebacker Ashlee Palmer missed practice with an ankle injury according to the Detroit Lions' official practice report Thursday.
He was one of four Lions to miss practice, joining defensive tackle Nick Fairley (shoulder), right tackle Jason Fox (groin) and safety Don Carey (hamstring).
If Palmer were to miss Sunday's game, he would likely be replaced by veteran Rocky McIntosh, although Tahir Whitehead is listed as his backup on the unofficial depth chart.
McIntosh was the fourth linebacker used in Detroit's 34-24 win over Minnesota on Sunday. It also means the Lions now have five healthy linebackers on the roster: starters Stephen Tulloch and DeAndre Levy, McIntosh, Whitehead and Travis Lewis.
Detroit coach Jim Schwartz declined to discuss the injuries to Fairley and Palmer, although he did not Fairley did finish Sunday's game.
Safeties Louis Delmas (knee) and John Wendling (ankle) were limited Thursday. Running back Reggie Bush and defensive end Jason Jones practiced fully.
