Despite a surprising 8-8 record, including going 6-0 in the AFC West, the Raiders chose not to renew head coach Tom Cable's contract at the end of the season. On Sunday, it became a little more apparent why that took place.

ESPN's Adam Schefter reported that Cable filed a grievance with the league, saying that team owner Al Davis unfairly fined him $120,000 over the course of 2010. The case will be settled by an arbitrator assigned by commissioner Roger Goodell.

The report states that Davis took $20,000 out of several of Cable's paychecks throughout the season, for reasons still not fully known. According to Schefter, the owner was not pleased the team lost two days of OTAs in June 2010, along with some other issues that Davis had with Cable.

This is not the first time Davis has had a disagreement with a coach over finances. Former coach Lane Kiffin filed a grievance against the owner in 2008, claiming Davis owed him money after he was fired following four games. A league-appointed arbitrator ruled in the Raiders' favor in November.
