USC quarterback Sam Darnold has signed with CAA Sports, the agency confirmed Friday.

Agents R.J. Gonser, Jim Dent and Jimmy Sexton will represent Darnold, one of the top prospects in the 2018 NFL Draft.

Sports Business Journal first reported the signing.

Darnold declared for the draft earlier this month, forgoing his final two seasons of college eligibility. He had started for the Trojans for two seasons and led them to their first Pac-12 Conference championship in nearly a decade in December.

Darnold, who is from Capistrano Beach, threw for a school-record 4,143 yards in his final season at USC, along with 26 touchdowns and 13 interceptions.

CAA Sports is also representing Wyoming’s Josh Allen, among the top quarterbacks to enter this year’s draft.

Darnold and Allen are training for the draft with former NFL quarterback Jordan Palmer in Orange County.

The NFL Scouting Combine begins in late February, followed by USC’s pro day workout later in the spring.

Sexton represents USC coach Clay Helton and offensive coordinator Tee Martin.
