CBSSports.com's Bruce Feldman has confirmed a report from Orangebloods.com that Texas defensive coordinator Manny Diaz has been fired.
The Longhorns gave up 679 yards of total offense against BYU on Saturday night, with the Cougars rushing for 550 yards. BYU quarterback Taysom Hill finished with 259 yards rushing while running back Jamaal Williams had 182 yards of his own.
It was an embarrassing performance for a Texas defense that had high expectations coming into the season as nine starters returned from last year's team.
Diaz came to Texas in 2011 from Mississippi State. In 2012 the Longhorns defense gave up 403.4 yards per game, the worst number in school history. Obviously, after Saturday night's performance Mack Brown was worried about seeing a repeat performance this year.
As for Diaz's replacement, CBSSports.com also confirmed that it will be Greg Robinson. Robinson last coached at Michigan as a defensive coordinator for two seasons and was the head coach at Syracuse from 2005 to 2008. Before that he was Texas' defensive coordinator in the 2004 season.
