Once running back Ricky Williams applies for reinstatement Tuesday, he might have to wait as many as 10 weeks for an answer. Medical advisers can take up to 45 days to submit an evaluation of Williams, who has been out of the NFL the past 18 months after being indefinitely suspended under the league's substance-abuse policy. Commissioner Roger Goodell then has 15 days to render a decision. The Dolphins have not said whether Williams will be allowed to return to the team.
