TEMPE, Ariz. — Athletic Director Mike Garrett, former football coach Pete Carroll and running backs coach Todd McNair were among the members of a USC contingent that was on the hot seat Thursday before the NCAA's Committee on Infractions.

Meanwhile, former USC tailback Reggie Bush, the focus of many of the allegations that landed USC in the desert for its long-awaited hearing, was at the Winter Olympics in Canada, preparing to take in a hockey game and some ski races.

USC representatives spent more than eight hours fielding questions from the 10-member infractions committee. The hearing, scheduled to continue through Saturday, is the culmination of a nearly four-year investigation that included allegations that Bush and former Trojans basketball player O.J. Mayo received extra benefits while competing for the Trojans.
