CHARLESTON , W.Va. — West Virginia University's board of governors has sued former football coach Rich Rodriguez to collect a $4 million buyout of his contract with the school.

The lawsuit, filed Thursday in Monongalia County Circuit Court, says the university believes Rodriguez doesn't intend to abide by the contract.

The buyout clause requires Rodriguez to pay $4 million to WVU over a two-year period, with one-third of the total due 30 days after his employment's termination. His resignation was effective Dec. 19.

Rodriguez went to Michigan after seven seasons in Morgantown, where he led West Virginia to four Big East championships and a 60-26 record.

Rodriguez and the university agreed to a seven-year contract on Dec. 21, 2002, and it has been extended twice since then. The latest revision was agreed to on Dec. 8, 2006, when Rodriguez was considering an offer from Alabama. The revised contract was to run through the 2013 season.

In addition to increasing Rodriguez's salary, the 2006 contract extension included a $100,000 supplemental payment to the assistant coaches' salary pool and $6.2 million in improvements to the team's athletic building, the Milan Puskar Center.
