Heisman Trophy winner Cam Newton is working with quarterbacks coach George Whitfield Jr. leading up to the NFL combine.

One of Newton's agents, Bus Cook, said Monday that Newton is in San Diego, Calif., with Whitfield, who worked with Pittsburgh Steelers quarterback Ben Roethlisberger during his four-game suspension.

Newton, who is skipping his senior year to enter the draft, led the Tigers to a Southeastern Conference national championship during his lone season in Auburn.

He won the Heisman and Maxwell player of the year awards, along with the Davey O'Brien and Manning awards as the top quarterback.
