Matthew Stafford took multiple big hits against the Packers on Sunday, including from defensive linemen Dean Lowry and Kenny Clark. Those blows knocked Stafford out of the game.
Stafford headed off the field to the locker room at the end of a Detroit drive after Clark landed on him at the end of a scramble. Stafford eventually returned to the sideline and made some warmup throws, but the next time the Lions' offense took the field, Chase Daniel was in at quarterback. Detroit later announced Stafford was questionable to return because of injured ribs, but Stafford did not return.
The 12-year Lions quarterback hasn't had a recorded rib injury during his NFL career, according to Sports Injury Predictor. His main health issue during the 2020 season has been a ligament problem in his throwing thumb.
