Quarterback Tim Tebow combined with the University of Florida's swarming defense to give the Gators a 13-3 win over Louisiana State in college football Saturday. Two weeks after suffering a concussion that had him in doubt for the game, Tebow led the defending national champions and No. 1-ranked team past their toughest regular-season test, beating the No.4-ranked Tigers. By the time it was over, Tebow had thrown a touchdown pass and Florida's defense had sacked opposing quarterback Jordan Jefferson five times. The crowd of 93,129 was the biggest in LSU's history. No. 2 Texas 38, Colorado 14: In Austin, Texas, Earl Thomas returned an interception 92 yards for a touchdown and Ben Wells recovered a blocked punt for another score to help Texas pull away from Colorado in the second half. Jordan Shipley returned a punt for a touchdown in the fourth quarter for the Longhorns, who can now look ahead to next weekend's showdown with No. 19 Oklahoma. No. 3 Alabama 22, No. 20 Mississippi 3: In Oxford, Mississippi, Mark Ingram rushed for 172 yards and a touchdown and Alabama downed Mississippi. Arkansas 44, No. 17 Auburn 23: In Fayatteville, Arkansas, Michael Smith rushed for 145 yards and a touchdown, and Arkansas held off a late Auburn rally to hand the Tigers their first loss. No. 5 Virginia Tech 48, Boston College 14: In Blacksburg, Virginia, Tyrod Taylor, Ryan Williams and Virginia Tech's defense made sure the Hokies' regular season losing streak against Boston College ended. No. 9 Ohio State 31, Wisconsin 13: In Columbus, Ohio, Kurt Coleman and Jermale Hines returned interceptions for touchdowns and Ray Small brought a kickoff back 96 yards, dealing the self-destructive Badgers their first loss of the season. No. 10 TCU 20, Air Force 17: At Air Force Academy, Colorado, Andy Dalton and TCU slid their way through the icy mist, the freezing cold and the Air Force defense to keep their BCS hopes alive with a dicey win over the Falcons. No. 11 Miami 48, Florida A and M 16: In Miami, already trailing the Miami Hurricanes by three touchdowns, Florida A and M tried lining up on defense with 13 players, but was still thrashed by Miami. No. 12 Iowa 30, Michigan 28: In Iowa City, Iowa, Ricky Stanzi threw for 284 yards and two touchdowns and Iowa survived yet another close call, beating Michigan for its best start since 1985. Elsewhere it was: No. 13 Oregon 24, UCLA 10; No. 14 Penn State 52, Eastern Illinois 3; No. 15 Oklahoma State 36, Texas A and M 31; No. 16 Kansas 41, Iowa State 36; No. 18 BYU 59, UNLV 21; No. 19 Oklahoma 33, Baylor 7; No. 22 Georgia Tech 49, Florida State 44; No. 25 South Carolina 28, Kentucky 26.
