Herschel Walker reveals mutiple personality disorder

The 1982 Heisman winner will reveal that he has multiple personality disorder in his new book, "Breaking Free" which is scheduled for release this August.

ESPN reports that a publicist at Simon & Schuster, which is publishing the book, said that "Breaking Free" will cover Walker's life with the disorder.

Walker was ranked third on ESPN's list of the greatest college football players ever. Many close to him were surprised to hear the the news.

Former Georgia coach Vince Dooley told the paper "That's all news to me. All I know is whatever personality he had when he had the football was the one I liked."
