There is some precedent for quarterbacks making a return to the NFL at age 35 or older. Tom Brady announced his retirement in February 2022 only to announce his return 40 days later. Brett Favre retired and returned multiple times prior to his final NFL season in 2010. But neither of those situations involved Carr's shoulder injury.

Derek Carr sent shockwaves through the NFL on Saturday when he made the decision to retire after 11 seasons. Although he's now done with football, it doesn't look like Carr is going to have much free time on his hands.

Derek Carr ran out of gas. Carr, 34, announced Saturday that he is retiring from the NFL rather than undergoing shoulder surgery —to repair a labral tear and damage to his rotator cuff — that likely would have ruled him out for the season.
