Barkley was selected in the fourth round of the NFL draft after a standout career at Southern California. The move announced Thursday leaves only one draft pick unsigned.
Barkley rewrote the conference record book during a USC-record 47 starts over four seasons, becoming the Pac-12's leader in touchdown passes, yards passing, completions and total offense.
He's competing with Michael Vick and Nick Foles for the starting job.
