Looks like he's not coming back after all.

Williams rejects NFL's deal allowing his return

MIAMI - Ricky Williams rejected a deal that would have allowed him to serve a four-game drug suspension this season and return to the NFL next year.
"Ricky indicated to me that he is no longer interested in resuming his career at this time," Williams' lawyer, David Cornwell, said in a statement e-mailed to The Associated Press on Thursday.
The 1998 Heisman Trophy winner from the University of Texas needed to let the league know by Thursday so he could be moved from the retired list to the suspended list by the deadline. He would have served the suspension for the Miami Dolphins' final four games, starting Dec. 12 at Denver.
"David Cornwell informed our office that Ricky Williams has declined to accept the terms of his reinstatement," NFL spokesman Greg Aiello said.
Dolphins spokesman Harvey Greene wouldn't comment, saying the matter is between Williams and the NFL.
Williams, 27, stunned his team by retiring shortly before Miami opened training camp in July. The Dolphins filed a lawsuit in federal court against the running back, seeking the $8.6 million an arbitrator ruled he owes the team for breaching his contract. Williams is fighting the decision.
He is now enrolled in a 17-month course at the California College of Ayurveda in Grass Valley, Calif., studying holistic medicine.
