Wingard (knee) has been ruled out for Sunday's game against the Lions, Bo Brack of GoPHNX.com reports.
Wingard was held out of practice all week due to a bone bruise in his knee, which he sustained against the Giants in Week 4. Wydett Williams figures to start alongside Budda Baker at safety due to the absence of Wingard, whose next chance to play is Week 6 against the Rams on Sunday, Oct. 18.
