Foles suffered the injury late in the first quarter.
Jaguars starting quarterback Nick Foles broke his left clavicle during Sunday's loss to the Chiefs, coach Doug Marrone announced.
Foles was ruled out for the remainder of the team's game with a left shoulder injury in the first quarter. He will be out indefinitely with the injury, but Marrone was not sure if it would be a season-ending injury. Foles spoke to reporters following the 40-26 loss and said he would have surgery on Monday.
Foles was knocked out of the game after being leveled by a pair of Chiefs defenders on the first touchdown throw of his Jacksonville career, a 35-yard pass to DJ Chark. The Super Bowl LII MVP was sent straight to the X-Ray room with trainers following the injury to be evaluated.
Foles was 5-of-8 passing for 75 yards and a score before exiting the game. The eighth-year QB signed a four-year, $88 million deal with the Jaguars in free agency.
Backup quarterback Gardner Minshew II took over for Jacksonville. He was drafted by the Jaguars in the sixth round in the 2019 NFL draft out of Washington State.
