Bears QB Room in Freefall: Bagent Concussion Leaves Chicago With Case Keenum as Fallback

The Chicago Bears' quarterback depth chart collapsed in real time on Tuesday. Tyson Bagent, the team's backup, entered the NFL's concussion protocol following his stint in Sunday's 9-3 loss to Minnesota, per Ian Rapoport. With Caleb Williams already sidelined by a right hamstring injury that coach Ben Johnson labeled "week-to-week," the Bears are staring at a scenario in which Case Keenum—a 35-year-old journeyman who hasn't thrown a pass in an NFL regular-season game in nearly three years—could be pressed into action Monday night against the Eagles.

Bagent was a late casualty from Sunday. The exact moment he sustained the concussion remains unclear, but the final play offers a telling window: on the game's last snap, Dallas Turner of Minnesota bulldozed through tight end Colston Loveland, who was forced into a one-on-one assignment, and reached Bagent in the pocket. That hit came after Bagent had already completed 5-of-9 passes for 54 yards—a forgettable day that now carries consequence because there is no reliable alternative waiting in the wings. Bagent has been Chicago's primary backup since signing as an undrafted free agent in 2023. His departure from availability pushes a third-stringer into the conversation.

Williams' prognosis remains the critical variable. Johnson refused to rule him out for the Eagles matchup, citing his player's uncommon capacity for recovery and his demonstrated willingness to fight through injury. An MRI on Monday morning delivered what Johnson called "somewhat encouraging" news on the hamstring, but the coach also stated plainly that he does not expect Williams to practice this week—a signal that availability is contingent on last-minute medical clearance, not confidence in full preparation.

For bettors, the Philadelphia line and passing prop markets are now pricing a genuine quarterback instability event. If Williams is declared inactive by Saturday, the Eagles defense faces a Case Keenum who has thrown 15 touchdown passes against 27 interceptions over his career and whose last meaningful action came in 2023. The Bears' team passing total, currently built around Williams' season average (269 yards through two games), will contract sharply if Keenum gets the start—expect that total to drop 40-50 yards from its current open. Keenum's historical per-game passing average sits around 198 yards; in a game where Philadelphia's defense allows just 214 passing yards per contest this season, the under on Chicago's team passing yards becomes a structural play, not a directional one. The Eagles' pressure rate also ranks in the top 10 of the league, a variable that will punish a pocket-management issue that Keenum's three-year absence will only amplify. Early-week uncertainty favors the market's adjustment to Keenum availability; by Friday, when the Bears formally announce the QB situation, the line will already be reflective. The angle exists now, on Tuesday, when a Williams-starting assumption still inflates the passing totals.
