Former Super Bowl champion Corey Dillon is experiencing a case of divorce deja vu ... 'cause his longtime wife is calling off their marriage ... for the second time.

The former New England Patriots running back has been hit with divorce papers from his wife of 12 years, Desiree Antoine-Dillon.

According to the docs, filed in L.A. County Superior Court and obtained by TMZ, Desiree is blaming the split on irreconcilable differences.
