FLINT, Mich. (AP) Ex-NFL player Andre Rison, who's accused of violating his probation in a child support case, says he'll turn himself in after a judge in Michigan signed an arrest warrant for him.

Rison tells the Detroit Free Press (http://on.freep.com/2aYqlJb ) he's a good father and his legal troubles are ''a big nasty hurdle.''

The warrant signed Tuesday by a federal judge says Rison recently tested positive for marijuana and failed to keep up with minimum support payments. Rison says he's used marijuana candy to deal with post-NFL injuries.

Rison was a star Michigan State receiver. He played for seven NFL teams from 1989 to 2000. He's lately been a high school coach in Flint and Ann Arbor.
