The Detroit Lions may be without two of their starters when the team takes on the Arizona Cardinals this coming Sunday.
Tight end Brandon Pettigrew and defensive tackle Nick Fairley were both injured in last week's loss to the Green Bay Packers and are listed as doubtful for Sunday's contest.
Pettigrew hurt his ankle and Fairley injured his shoulder in the defeat, preventing either player from practicing all week.
Neither player has missed a game all season, with Fairley recording 34 tackles, 5 1/2 sacks and two forced fumbles while Pettigrew has notched 57 catches, 556 yards and three touchdowns through 13 games.
Safety Louis Delmas, who practiced in a limited capacity on Thursday but was held out of Friday's session, is listed as questionable with a knee injury.
