Alameda, Calif. ? Former Oakland Raiders coach Lane Kiffin filed a grievance with the NFL on Wednesday to claim the lost salary he maintains he is still owed by the team. Kiffin was fired late last month for cause because of what owner Al Davis described as acts of insubordination and lying by his second-year coach.

Kiffin was still owed about $2.6 million from the three-year contract that he signed in January 2007. But Davis has refused to pay, leading to the grievance. Commissioner Roger Goodell will ultimately rule on the grievance, but there was no date for a hearing scheduled.
