Texas and USC dropped out of Associated Press Top 25 college football poll after ugly losses, and the Longhorns fired their defensive coordinator less than 24 hours later.
Alabama, which was still No. 1 after an off week, plays at No. 6 Texas A&M on Saturday. Oregon was No. 2, followed by Clemson, Ohio State and Stanford.
Texas lost at BYU 40-21, a defensive effort that cost Manny Diaz his job Sunday. The Cougars ran for 550 yards against then 15th-ranked Texas. Coach Mack Brown said former Longhorns defensive coordinator and Syracuse coach Greg Robinson will take over the job.
The Trojans were No. 25 before a 10-7 home loss to Washington State.
"That's not a performance that anybody should have to pay to see," USC coach Lane Kiffin said.
NASCAR will review whether Michael Waltrip Racing deliberately altered Saturday's race in Richmond, Va., potentially costing Ryan Newman and Jeff Gordon spots in the Chase for the Sprint Cup championship, to benefit MWR's Martin Truex Jr. Clint Bowyer's suspicious spin with seven laps left brought out a caution while Newman was leading. "We had a flat tire or something," Bowyer said.
Cal's Michael Kim and Stanford's Patrick Rodgers won second-day singles matches, helping the United States to a 17-9 rout of Britain & Ireland in the Walker Cup at National Golf Links of America (N.Y.). Also, Kim and former Cal teammate Max Homa won a foursome match. Kim finished 3-0.
Carolina fired the son of NHL team owner Peter Karmanos Jr. Jason Karmanos was executive vice president. Peter said it was "a family matter" and declined further comment.
