Texas fires defensive coordinator Manny Diaz

Texas fired defensive coordinator Manny Diaz on Sunday, less than 24 hours after one of the worst defensive performances in the history of the program.

Longhorns coach Mack Brown announced that former Longhorns defensive coordinator and Syracuse coach Greg Robinson will take over the job.

‘‘Our performance on defense [Saturday] night was unacceptable, and we need to change that,’’ Brown said.

BYU ran for 550 yards, the most ever allowed by Texas, in a 40-21 victory, putting a potential breakthrough season on the brink of another big disappointment if the Longhorns can’t fix their defensive problems.

Texas (1-1) plays No. 25 Mississippi (2-0) at home on Saturday.

Kiffin hears it

Fans in cardinal-colored jerseys leaned over the railing and bellowed their boos into the Coliseum tunnel. Negative chants rained down on the coach as he ran to the locker room after each half.

Only Southern California’s fans weren’t booing the opposition in the Trojans’ home opener. They’re already fed up with Lane Kiffin and a night of historical ineptitude by his offense.

Andrew Furney kicked a 41-yard field goal with 3:03 to play, and Washington State beat No. 25 USC, 10-7, Saturday night for its first victory at the Coliseum in 13 years.

Kiffin’s two-quarterback offense managed just 193 yards on 63 plays, with no pass completion longer than 8 yards. The Trojans also missed a field goal and had another blocked after scoring their only touchdown on an early 22-yard drive set up by their dominant defense, which has nearly shut out two straight opponents.

‘‘You can’t worry about that,’’ Kiffin said of the chants. ‘‘I think I heard those before the game started, during warm-ups, so I'm used to it. When you don’t play well, it falls on the head coach. We obviously weren’t well-prepared on offense.’’

The Trojans play Boston College Saturday in Los Angeles.

UCLA player killed

UCLA freshman wide receiver Nick Pasquale was struck by a car and killed while walking in San Clemente, Calif. He was 20. The Orange County Sheriff’s Department reports that Pasquale was struck about 1:30 a.m. Sunday. It wasn’t immediately clear if he was trying to cross a street. However, Sheriff’s Lieutenant Gary Strachan says the car’s driver stopped, called authorities, and stayed with Pasquale until they arrived. The accident is under investigation . . . Duke quarterback Anthony Boone is out indefinitely with a broken collarbone. Coach David Cutcliffe said Boone does not need surgery to repair the broken bone, but has no timetable for his return . . . Cincinnati quarterback Munchie Legaux was transferred to a Cincinnati hospital after a gruesome left knee injury against Illinois.

Miami back in Top 25

Miami is ranked for the first time since November 2010. The Hurricanes jumped all the way to No. 15 after beating Florida, 21-16. The ‘Canes are 15-11 under coach Al Golden, but have yet to go to the postseason, thanks to a self-imposed ban the school put in place as punishment for the improper benefits investigation that the NCAA has yet to rule on . . . Tyler Gaffney ran for 104 yards and two TDs in an impressive return after playing baseball in the minors last year, leading No. 5 Stanford past gritty San Jose State, 34-13, late Saturday night in its season opener at Stanford, Calif. The Cardinal scored on their first three possessions.
