Keenum (coach's decision) is inactive but serving as the Bears' emergency third quarterback against the Vikings on Sunday.
Tyson Bagent was inactive for Week 1 against the Panthers but has been cleared to play for Week 2, so he'll serve as the Bears' backup quarterback for Caleb Williams while Keenum serves as the emergency QB3. As such, Keenum is prohibited from playing in Sunday's game unless both Williams and Bagent were to leave the game due to injury, illness or ejection.
