IRVINE, Calif. (AP) Former USC and Los Angeles Raiders quarterback Todd Marinovich has been arrested after being found naked with marijuana and possibly methamphetamine in a stranger's backyard in Southern California.

Irvine Police Cmdr. Mike Hallinan said Monday that Marinovich was arrested Friday night after a call saying a naked man was on a hiking trail near homes. The officers found him in a backyard holding a brown bag containing marijuana and a substance that appeared to be meth but police are awaiting lab results.

The 47-year-old Marinovich was a star quarterback at USC and the Raiders' first-round draft pick in 1991, but drug problems drove him from the NFL after two seasons and he has had repeated run-ins with the law over drugs in the decades since.
