Greg McDermott is heading back to the Missouri Valley.

FOXSports.com has confirmed that the Iowa State head coach, who has spent the past four years in Ames after leaving Northern Iowa, has agreed to replace Dana Altman at Creighton.

According to sources, McDermott has agreed to a 10-year deal worth $9 million and Creighton will also pay for buyout of $800,000.

An official announcement is expected on Tuesday.

McDermott led Northern Iowa to three consecutive NCAA tournament appearances before taking the job at Iowa State four years ago -- where he has compiled a 59-68 record.

The Cyclones were 15-17 this past season and would have a difficult time moving up in the Big 12 with the loss of potential first-round pick Craig Brackins and the team's second-leader scorer, Marquis Gilstrap. There were also several other players who have decided to leave the program -- including Lucca Staiger (overseas), Justin Hamilton (LSU), Chris Colvin and Dominique Buckley.

There was also a staff shake-up as Ron Smith retired.

McDermott will go from one of the most difficult Big 12 jobs to arguably the top one in the Missouri Valley.

He is also familiar with the state of Nebraska having coached at Wayne State for six seasons.
