The Detroit Lions were without a pair of starters in practice on Thursday, as defensive tackle Nick Fairley and tight end Brandon Pettigrew sat out.
Fairley sat out with a shoulder injury, while Pettigrew is nursing an injured ankle. Both players suffered the injuries during Detroit's loss to Green Bay on Sunday. Fairley was injured late in the game, while Pettigrew suffered his ankle injury during the first quarter then missed the rest of the game.
If both players are unable to play against Arizona, they would be major losses for the Lions. Fairley is one of Detroit's best defensive players, while Pettigrew is the Lions' second-leading receiver behind Calvin Johnson. Pettigrew is second to Johnson with 57 receptions this season. Running back Joique Bell is the only other active Lion with more than 30 receptions.
The Lions did get some good injury news on Thursday, as both safety Louis Delmas and cornerback Chris Houston returned after missing practice on Wednesday. The complete injury report can be found on the Lions' official website.
