INDIANAPOLIS — Gonzaga got on a roll and put on a show Tuesday night, moving to 30-0 on the season and cruising into the Final Four with an 85-66 beatdown of previously rolling Southern California.

Drew Timme had 23 points and five rebounds and, after one dunk, pretended to slick down his handlebar mustache for the few thousand fans in the stands. The top-seeded and top-ranked Bulldogs will be the third team to bring an undefeated record into the Final Four since the bracket expanded to 64 teams in 1985.

The last team to go undefeated was Indiana in 1976.

Official Bert Smith collapsed on the floor early in the Elite Eight game between Gonzaga and Southern California and had to be taken off the court on a stretcher.

Smith had just set up on the baseline as the Trojans were moving onto offense when he collapsed and hit his head on the floor.

He stayed down for about five minutes, and then was able to stand up and move to a nearby stretcher. He was alert and sitting up with his arms crossed as he was taken off the court.

On the CBS broadcast, rules analyst Gene Steratore said Smith was feeling “lightheaded,” leading to the fall. He said Smith was being treated by trainers in the locker room and is stable.

Smith was officiating his second Elite Eight. He was replaced by an alternate, William Henderson, who had been at the scorer's table.
