AUSTIN (KXAN) - Less than 24 hours after an embarrassing 40-21 loss on the road to BYU, Manny Diaz was fired as Texas' defensive coordinator Sunday.
Former UT co-defensive coordinator Greg Robinson will take over for Diaz.
"Our performance on defense (Saturday) night was unacceptable, and we need to change that," head coach Mack Brown said.
Texas surrendered 679 yards of total offense to the Cougars in the loss, including 550 on the ground.
Diaz will be reassigned to a position within the athletics department, according to Brown.
"Greg will be here (Sunday) and get with the staff and players to start preparing for Ole Miss. He will be running our defense immediately."
Robinson brings in 36 years of coaching experience and has served as a defensive coordinator on two Super Bowl winning teams, and the Longhorns' 2004 Rose Bowl Championship squad. He began a stint as a football analyst with Texas in July.
"We're very fortunate that Greg has been around, watched all of our practice video and has a good scouting report moving forward, Brown said. "His familiarity with the staff and players should make for a smooth transition. He knows this place, did a terrific job in leading our defense before, and I'm excited to have him back on the field. We're back at it and working hard to beat Ole Miss this weekend."
The Longhorns entered the season with high expectations and were ranked 15th going into Saturday's game at BYU with Diaz set to improve a defense that ranked sixth in the Big 12 and 73rd in the nation in scoring defense, allowing more than 29 points per game. Instead, many of the same problems that plagued the team last year were pushed to the forefront once again.
Following the loss, the Longhorns dropped out of the Top 25.
Robinson most recently served in coaching as the defensive coordinator at Michigan for two seasons (2009-10) after spending four years as the head coach at Syracuse (2005-08).
"This is a tough deal for everyone involved, but I love The University of Texas, and Coach Brown has been wonderful to me," Robinson said. "I'll do anything I can to help him, so when he called, I told him I'd be there today. I know the staff, have a lot of respect for them and am excited for the challenge moving forward."
Prior to Texas, Robinson spent 10 of his 14 years coaching in the NFL as a defensive coordinator with the Kansas City Chiefs (2001-03), Denver Broncos (1995-2000) and New York Jets (1994). He was the Jets' defensive line coach for four seasons (1990-93) prior to his appointment as defensive coordinator.
"I've been around the team a lot, watched all of their film and have been self scouting and scouting opponents since I came on board in July. Because of Longhorn Network, I've also been able to see these guys for two to three years and am very familiar with the personnel.
"Having coached here, I do know the ins and outs and having the stability with the rest of the staff will be very beneficial."
