OWINGS MILLS, Md. (AP) -- Ricky Williams has told the Ravens that he's retiring from football.
The 34-year-old running back still has a year left on his contract with Baltimore.
After winning the Heisman Trophy at Texas, Williams broke into the NFL in 1999 with the New Orleans Saints. His 1,853 rushing yards in 2002 with the Miami Dolphins led the NFL.
Williams retired before the 2004 season when facing a four-game suspension for violating the league's drug policy. It lasted one year.
Williams had five 1,000-yard rushing seasons over 11 years.
He ran for 444 yards and scored two touchdowns as a backup to Ray Rice in his first season with the Ravens.
