JACKSON, Miss. — Former New Orleans Saints running back Deuce McAllister has filed for bankruptcy protection for a car dealership he owns in Mississippi.

The free agent running back is in a dispute with Nissan's financing arm. Nissan says McAllister owes more than $6.6 million and nearly $300,000 in interest.

The company says McAllister defaulted on a deal, then exceeded his credit line.

McAllister said Tuesday he filed for bankruptcy to protect his inventory and is searching for an investor.

The 2001 first-round draft pick was released by the Saints in a salary cap move last month and is now looking for a new team. He was due $7 million next season.

McAllister also owns a luxury vehicle dealership in Jackson.
