Muschamp said earlier on Friday that he had not made a decison and would not make one until he met with Tuberville following a visit to Austin, Tex. for an interview with Coach Mack Brown.
Tuberville, who told Inside the Auburn Tigers that he is already getting plenty of interest in the defensive coordinator post, is flying to California this week for the annual national coaching convention that will be held in Orange County.
Muschamp was in Austin with his wife Carol on Thursday and Friday to interview with Coach Mack Brown for a co-coordinator position on the University of Texas coaching staff. Texas previously hired an AU defensive coordinator, Gene Chizik, after the 2004 season. Chizik left Texas last year to take over as head coach at Iowa State.
Muschamp's 2007 Auburn defense was ranked among the nation's best in a variety of categories. The Tigers gave up 16.9 points and 297.9 yards per game and finished 9-4 with a Chick-fil-A Bowl victory over Clemson.
Muschamp was previously in the mix for the head coaching positions at Southern Miss, Georgia Tech and Arkansas. He took his name out of consideration at Southern Miss before that college made its pick.
Muschamp, who played football for the University of Georgia, began coaching as a graduate assistant at Auburn in 1995-96. He coached the secondary at West Georgia in 1998 and Eastern Kentucky the following season. He got his first defensive coordinator post at Valdosta State in 2000, where he spent one season before moving to LSU.
He coached linebackers at LSU, where he was also defensive coordinator. Following the 2004 season he spent one year as assistant head coach for defense with the Miami Dolphins before coming to Auburn as defensive coordinator in 2006.
Muschamp was a finalist for the Frank Broyles Award, which is presented annually to the nation's top assistant coach.
We're thrilled to have Will joining our staff," Texas coach Mack Brown said. "He's a bright, young, high-energy coach who has gained a great deal of experience and had a lot of success in working for three tremendous coaches in Nick Saban, Tommy Tuberville and Roy Kidd. He built a defense at LSU that helped them become one of the nation's most dominant units for several years, including a National Championship in 2003, and he's done the same thing at Auburn.
"Greg Davis and Mac McWhorter both know Will very well having worked with him as a player at Georgia and they both highly recommended him." Brown said. "Our entire staff had a chance to spend some time with him on Thursday and all really enjoyed him. They all agreed that he'd be the perfect fit for us. He has a great personality, a terrific family and is one of the bright young stars in our business. We're anxious to get him here, working together with our defensive staff."
