The Tigers, chosen as preseason Atlantic Coast Conference champions, landed ninth in the first coaches' poll hours before they opened fall camp.
"I wouldn't have any idea this early in the preseason whether that'd be an accurate ranking," Clemson coach Tommy Bowden said. "I know it's something that's not very significant until the end of the year, and that's what we talked about with the team."
South Carolina and coach Steve Spurrier also took the practice field for their opening drills. The Gamecocks enter the season on a five-game losing streak that turned their 6-1 start into a .500 year.
OKLAHOMA: An incoming freshman player was dismissed from the team by coach Bob Stoops after a video of him rapping about guns and shooting people appeared on the Internet.
The dismissal of wide receiver Josh Jarboe came after the player appeared in a 74-second, profanity-laced video.
The 6-foot-3, 195-pound Jarboe signed with the Sooners in February. In March, he was arrested after an assistant principal at Cedar Grove High School in Ellenwood, Ga., told a school police officer he saw Jarboe grab a gun from a car.
Jarboe was expelled from school but completed his high school degree online.
NORTH CAROLINA: Two newcomers have not yet reported for the start of practice.
Coach Butch Davis said Friday as preseason camp began that freshman linebacker Kevin Reddick and junior-college transfer Joseph Townsend aren't with the team.
Davis said Reddick was sitting out because of an issue with the NCAA's clearinghouse and hopes to have it resolved "in the very immediate future."
The reason for Townsend's holdup is because junior colleges in California have yet to finish their summer-school sessions, thus he's finishing classes.
Both players figure to be in the mix on defense for the Tar Heels.
ARMY: Coach Stan Brock watched his team's opening practice from a golf cart Friday after having follow-up treatment for prostate cancer.
Brock, 50, said in a statement that he was diagnosed with prostate cancer during a routine physical in July and underwent successful surgery Tuesday.
"Fortunately, it appears the doctors were able to diagnose things early and they expect me to enjoy a complete recovery," Brock said.
COURTS: In San Diego, a sports marketer's civil suit against former Heisman Trophy winner Reggie Bush will proceed in open court instead of going to a confidential arbitration, a judge ruled Friday.
Lawyers for the New Orleans Saints running back petitioned to move the case into closed proceedings in San Francisco, in part to shield Bush from public attention.
Attorneys for marketer Lloyd Lake argued that the former Southern Cal star was trying to hide details from NCAA investigators about improper gifts he allegedly took from Lake's New Era Sports agency while playing for the Trojans.
