The Lions have listed Stafford as questionable twice in 2019.
Stafford has broken bones in his back, according to ESPN's Adam Schefter.
Stafford has been on the injury report since Week 4 with a hip issue, but he had only been limited in one practice - back on September 27 - until this week, when the back injury also popped up.
Jeff Driskel is likely to start in Stafford's place, with David Blough backing him up.
Stafford's back injury is not new. "Any player that's had to miss any amount of time, whether it's one game, a quarter, even a series from injury, they feel like, 'Okay, when I get back out here, I got to get rolling'". However, a last-minute spot start against the Bears at Soldier Field figures to be a hard assignment, even with Chicago's defense not playing at the same level as years past. He had been listed as questionable on the injury report and was practicing through the week while hoping to play through the pain.
There is a possibility that the Lions shut Stafford down for the rest of 2019. "I'm not really anxious about that. Something different, but I'm totally good".
Most agree the now watered down Pro Bowl is a poor litmus test for successful players, but Stafford could be heading for the game and potentially for an All-Pro nod as well if he keeps up his huge play so far this season.
Stafford's wife, Kelly, posted a tribute to her husband on Instagram on Sunday morning. However, in the week before the Bears game, Stafford was practicing through pain and telling reporters he was fine.
