New Jacksonville Jaguars quarterback Nick Foles' season is already in jeopardy.

The Jaguars prized off-season addition broke his left clavicle in the team's 40-26 season-opening loss to the Kansas City Chiefs on Sunday, the team has announced. It is not yet known how long the quarterback will be out for, as he will undergo surgery on Monday.

Foles suffered the injury on a play where he threw a 35-yard touchdown to DJ Chark. After Foles threw the ball, he took a hit from Chiefs defensive tackles Chris Jones and subsequently landed on his shoulder.

The 30-year-old Foles, who is a former Super Bowl MVP, signed a four-year deal worth a reported $88 million with Jacksonville in the off-season.
