Ihedigbo said earlier this week he has been resting as the reason he sat out the Lions' final two preseason games and also practices this week leading up to Detroit's season-opener against the New York Giants on Monday night.
He insisted he'd be ready to play Monday night, but now his rest is officially more than just a footnote. It will be interesting to see what it says when the Lions' first injury report is released later Thursday.
But if Ihedigbo isn't able to play for some reason, that could mean Jerome Couplin, an undrafted free agent rookie out of William & Mary, might be in line for his first start in his first game. Couplin has been listed as the No. 2 strong safety behind Ihedigbo instead of Isa Abdul-Quddus, who started in Ihedigbo's place the last two preseason games.
The Lions are looking fairly thin at safety now as well, as Don Carey continued to miss practice with a hamstring issue.
If neither player goes Monday night, that leaves Detroit's safeties as Glover Quin, Abdul-Quddus and Couplin.
Cornerback Champ Bailey, who worked out for the Lions on Thursday, was not spotted at practice.
