The group that crowns college football's national champion stripped the 2004-05 title from the University of Southern California on Monday, a decision stemming from an NCAA investigation of former USC running back Reggie Bush.
No 2004 champion will be named in USC's place, the Bowl Championship Series said.
The BCS's decision was a distinct possibility since last year, when the NCAA vacated USC's last two victories of the 2004 season and all of the Trojans' wins in 2005 after ruling that Bush violated rules by accepting gifts while at USC.
The group said it made its decision after the NCAA denied USC's appeal of sanctions last month.
"This action reflects the scope of the BCS arrangement and is consistent with the NCAA's approach when it subsequently discovers infractions by institutions whose teams have played in the NCAA championship events," BCS Executive Director Bill Hancock said in a news release.
The BCS also stripped USC of the January 2005 Orange Bowl victory that clinched the 2004 title, and vacated USC's appearance in the 2006 Rose Bowl, which it lost to Texas.
"This was not an unexpected outcome," USC athletic director Pat Haden said, according to USC's athletics site. ¬†"We will comply with all requirements mandated by the result of this BCS vote."
The NCAA ruled last year that Bush lost his eligibility to play college football in December 2004, saying that he and his family accepted gifts from two would-be sports agents.
The agents, hoping to represent Bush in the NFL draft, allegedly paid for hotel rooms, rent on a home where Bush‚Äôs family lived and a limousine ride that Bush took to accept the 2005 Heisman Trophy. Such payments and gifts are not allowed under NCAA rules.
Bush played for USC from 2003 through January 2006. He left school as a junior, and the New Orleans Saints drafted him in the 2006 NFL draft.
Besides vacating victories, the NCAA last year put USC on four years of probation, banned it from bowl games in the 2010 and 2011 seasons, and ruled that USC cannot associate itself with Bush.
Bush forfeited his 2005 Heisman Trophy last September, a few months after the NCAA sanctioned USC.
The decision to not crown a 2004 champion may disappoint Auburn, Oklahoma and Utah fans. Auburn, like USC, finished the season 13-0, and was ranked No. 2 in that season‚Äôs final, post-bowl Associated Press poll.
Oklahoma lost to USC in the Orange Bowl, 55‚Äď19, and finished third in the AP poll. Utah finished the year 12-0 and was ranked fourth by the AP.
The Associated Press last year decided not to alter its 2004-05 rankings, meaning USC remains atop that year's final poll.
