South Carolina vs. Florida
Florida is considered one of the hottest teams in college football, as they have won their last five games by an average of 39 points. South Carolina coach Steve Spurrier would love to knock off his alma mater out of this year’s BCS championship title hunt. And he will try to defeat the Gators by rotating quarterbacks (Stephen Garcia and Chris Smelley) on every offensive play. The rotation system did not seem to bother either quarterback in last week’s 34-21 victory over Arkansas; they combined to throw for 219 yards with two touchdown passes and only one interception. It will not matter how well the QB duo performs if the Gamecocks defense cannot contain Tim Tebow, he accounted for seven touchdowns in a 51-31 victory at South Carolina last season. National coverage will begin Saturday at 3:30 PM on CBS.

UFC 91: Randy Couture vs. Brock Lesnar for the UFC Heavyweight Championship Title
The main event of UFC-91 is a classic example of two contradictory styles going against one another, as Randy Couture puts up his heavyweight title against Brock Lesnar at the MGM Grand Garden Arena in Las Vegas. Lesnar is still untested as a fighter, as he going into only his fourth MMA fight this Saturday night. Couture is unstoppable coming into matches where he is an underdog with a 9-1 record. Lesnar is bigger, stronger, faster and hopes to neutralized Couture’s Greco-Roman wrestling style being a former NCAA wrestling champion himself. Couture has out-muscled larger opponents in his career and expects his experience to come into play in this fight. He hopes to avoid the takedown by moving side-to-side and using his hand speed and quick legwork to neutralize his opponent’s superior strength. If Lesnar can take Couture off his feet, the question will become: Can he keep him on the mat? Pay-per-view coverage will begin Saturday at 10:00 PM

Dallas Cowboys vs. Washington Redskins
The Dallas Cowboys hope the return of quarterback Tony Romo to the starting lineup will provide a spark and help them get a “W” in the win column this Sunday night in Washington. Since winning their first three games, the Cowboys have dropped four of their last six games and likely will need to win at least five of their final seven games to hopefully be considered for a playoff spot. Injuries could have a large role in determining if the Washington Redskins make the playoffs. They may have to go the rest of the season without running back Clinton Portis, who is second in the NFL in rushing with 995 yards. He injured his knee at the end of the first quarter against the Pittsburgh Steelers two weeks ago and has not returned to the lineup. National coverage will begin Sunday at 8:15 PM on NBC.
