Dolphins RB Ricky Williams Retires

MIAMI (AP) - Ricky Williams has decided to quit the game of football in his prime. He's told the Miami Dolphins that he's going to retire.

The decision leaves a void in the team's backfield one week before the start of training camp. Williams rushed for 3,225 yards in two season with the Dolphins. He leaves the game after just five seasons in the league.

Williams told the Miami Herald "you can't understand how I feel." Williams told the paper there is no way he will change his mind.

He's been known to be ambivalent about life in the sports spotlight.

Williams won the Heisman Trophy at Texas in 1998 and began his career with the New Orleans Saints. He played three seasons for the Saints, but didn't blossom until he went to the Dolphins.
