There are no guarantees Ricky Williams will be on Miami’s 2008 roster, but the Dolphins may soon have an opening for a new backup running back behind starter Ronnie Brown.

Jesse Chatman, who handled that role in 2007, is scheduled for a free-agent meeting Wednesday with the New York Jets.

Out of football for almost two seasons, Chatman resurrected his career last year by rushing for 515 yards and one touchdown. Chatman also started six games in place of the injured Brown (knee) before being maligned with ankle problems.

Williams started in place of the injured Chatman last November against Pittsburgh after being reinstated by the NFL following a 19-month drug suspension. Williams, though, suffered a torn pectoral muscle after just six carries in that game and missed the rest of the season.

Dolphins executive vice president Bill Parcells exercised a one-year option on Williams’ contract immediately after the season ended. The move insured Williams, 30, couldn’t opt out of his current deal and become a free agent.

Williams is now slated to earn a 2008 base salary of $730,000, which is the NFL-minimum base salary for a player with seven accredited seasons. It’s also a bargain if Williams can regain the form that made him one of the NFL’s top rushers before repeated drug suspensions derailed his football career.

The Dolphins selected Florida State running back Lorenzo Booker in the third round of last year’s draft. But Booker struggled for playing time as a rookie and, at 5-foot-11 and 191 pounds, may not have the size to handle an every-down role.

Coming off a torn anterior cruciate ligament, Brown is expected to return for the start of the regular season. Brown, the No. 2 overall pick in the 2005 draft, was enjoying his best NFL season before getting hurt.

New York’s interest in Chatman is curious simply because the team already has two solid running backs in Thomas Jones and Leon Washington. But Chatman also has value on special teams.
