Miami Dolphins running back Ricky Williams has been cleared by the NFL to report Sunday with the rest of the team for the start of training camp, a year and a day after he abruptly retired.

The league's 2002 rushing champion decided to seek reinstatement after sitting out last season. He still faces a four-game suspension at the start of the season for violating the NFL substance abuse program.

The NFL cleared Williams to report on the first day of camp without incurring a further violation of the drug program, league spokesman Greg Aiello said yesterday. Williams acknowledged shortly after retiring that he failed drug tests and faced a suspension for testing positive three times for marijuana.

Williams studied holistic medicine at a school in northern California from October to April and finished the first year of a three-year program, then spent April at a yoga center in India and became certified as an instructor, said his agent, Leigh Steinberg.

After retiring, Williams lost more than 20 pounds on a vegetarian diet. Steinberg said his weight is back above 215, still below his listed weight of 226 on the 2004 preseason roster.

Williams rushed for 3,225 yards and 25 touchdowns in two seasons with the Dolphins.
