AUSTIN, Texas (WTVA/AP) - After firing defensive coordinator Manny Diaz two games into the season, Texas coach Mack Brown says he's not panicking. He's trying to fix a problem.
Brown also insists the Longhorns' 40-21 loss to BYU didn't raise the pressure on his own job. Texas gave up a school-record 550 yards rushing and dropped out of the Top 25 with the loss.
Texas is (23-18) since 2009, but Brown had talked openly in the preseason that this year's experienced team could lead the Longhorns back to national prominence.
Texas wide receiver Daje Johnson, who the Longhorns are counting on as their big playmaker, will miss Saturday's game against No. 25 Ole Miss with a sprained left ankle.
Johnson scored two touchdowns in Texas' season-opening win over New Mexico State but was injured on the third play of last week's loss at BYU. Johnson's ankle twisted awkwardly when his leg was pinned under a defender.
Longhorns quarterback David Ash, who left the game in the fourth quarter after injuring his right shoulder and taking a knock to the head, is still being evaluated for this week's game.
The Longhorns left Provo after being embarrassed by BYU, leaving Brown scrambling to fix his defense. Diaz, who previously served as Mississippi State's defensive coordinator, was reassigned and the coordinators job was given to Greg Robinson, a former Longhorns and Michigan assistant who had also had a stint as head coach at Syracuse.
