Sports in Brief: NCAA hits USC with bowl ban

The University of Southern California has received a two-year bowl ban and a sharp loss of football scholarships in a report on the NCAA's four-year investigation of the school.

The NCAA cited USC for a lack of institutional control Thursday in its long-awaited report, which detailed violations primarily involving Heisman Trophy-winning tailback Reggie Bush and men's basketball player O.J. Mayo.

The NCAA found that Bush was ineligible beginning by December 2004, a ruling that vacates every win in which he participated, including the BCS championship game in 2005, and could open discussion on the revocation of the New Orleans Saints star's Heisman.

While coming down hard on the football team, the NCAA largely accepted the terms of USC's self-imposed punishment on its men's basketball team.

Colorado has decidedtoleave the Big 12 and join the Pac-10, as the college sports landscape began a much-anticipated shift.

Nebraska could become part of the Big 10 as soon as Friday, and speculation is heavy that Texas, Texas A&M, Texas Tech, Oklahoma and Oklahoma State may also jump to the Pac-10.

If the Big 12 is further raided as expected, that would leave Missouri, Baylor, Iowa State, Kansas and Kansas State out in the cold.

Any of these schools could be targets for the Mountain West Conference, which this week held off on inviting rising football power Boise State after speculation swirled about the possible unraveling of the Big 12.
