The Lions have listed Stafford as questionable twice in 2019.
There is a possibility that the Lions shut Stafford down for the rest of 2019.
Signed by the Lions in September, Driskel started five games for the Cincinnati Bengals last season, completing 59.7 percent of his passes and throwing for six touchdowns.
After the Bears game in Week 10, the Lions are scheduled to host the Cowboys in Week 11.
NFL Network reported during the day that there was concern about Stafford's status as he battles hip and back injuries, saying he "could be a real game-time decision". The 11th-year veteran and Lions' all-time leading passer was a limited practice participant this week, and per Schefter, was uncorking 60-yard throws during Friday's workout, making Sunday's news all the more stunning. Last week, Stafford spoke of texting with Atlanta Falcons quarterback Matt Ryan, whose streak was ended recently at 154 games by an ankle injury. In Week 4, versus the Kansas City Chiefs, he was questionable to play up until kickoff. However, in the week before the Bears game, Stafford was practicing through pain and telling reporters he was fine.
The next morning, Stafford evidently gave in to doctors' suggestions for further tests on his back. "I'm not really anxious about that. Something different, but I'm totally good".
Stafford's wife, Kelly, posted a tribute to her husband on Instagram on Sunday morning.
That Saturday, ESPN reported that Stafford was told not to play against the Bears, but that he hoped to overcome the pain as usual.
