MONTGOMERY, Ala. (AP) — A charter bus carrying home University of Alabama cheerleaders after the BCS championship game was involved in a wreck that seriously injured a student who was riding in another vehicle, officials said Wednesday.

Authorities said the crash happened about 10:20 p.m. Tuesday on Western Boulevard at Interstate 65 in Montgomery. Police said the accident involved the cheerleaders' bus, which was carrying 31 people; a pickup truck; and a car.

Lt. Regina Duckett, a spokeswoman for the Montgomery Police Department, said no one on the bus was hurt, but a passenger in the pickup suffered life-threatening injuries and was listed in stable condition.

University spokeswoman Deborah Lane said the injured person was a student who was riding with three other students. The four were not traveling with the cheerleaders' bus, she said.

Duckett said two people in the car suffered minor injuries.

Officials said the cheerleading squad was headed back to Tuscaloosa from the BCS title game in Miami, an 800-mile ride. The football team, which defeated Notre Dame 42-14 for its third football championship in four years, flew home earlier in charter jets.

Police were investigating the cause of the crash, Duckett said.
