ALLEN PARK, Mich. - Detroit Lions tight end Brandon Pettigrew and Nick Fairley missed practice all week, and both are listed as doubtful on the team's injury report for Sunday's game against the Arizona Cardinals.
Pettigrew injured his ankle in the opening moments of the Lions loss to Green Bay last Sunday night.
Fairley suffered a shoulder injury late in the same game. The Lions placed defensive tackle Corey Williams on injured reserve earlier in the week. Fairley had been starting in place of Williams the last five weeks.
Safety Louis Delmas sat out practice Friday with the knee injury that has plagued his season. He is questionable for Sunday.
Cornerback Chris Houston (hamstring), safety Don Carey (knee), wide receiver Calvin Johnson (knee), cornerback Jacob Lacey (foot/Achilles), and tackle Corey Hilliard (knee) are all listed as probable.
