BATON ROUGE, La. — Tim Tebow arrived at raucous Death Valley ready to play. Then No. 1 Florida's defense left No. 4 LSU in a daze.

Two weeks after suffering a concussion, Tebow and the Gators' swarming defense silenced the largest crowd in the history of Tiger Stadium with a 13-3 victory Saturday night.

The day began with Tebow's status uncertain for what looked like the defending national champions' toughest regular-season test.

By the time it was over, Tebow had thrown a touchdown pass and Brandon Spikes had a led Florida defense that sacked Jordan Jefferson five times.

Most of the 93,129 fans who partied all day and roared like a jet engine after kickoff were heading for the exits with 2½ minutes left.

Florida (5-0, 3-0 Southeastern Conference) has won 15 straight games, the best in the nation. LSU (5-1, 3-1) had its 32-game winning streak in Saturday night games snapped.

Tebow completed 11 of 16 passes for 134 yards with an interception, and ran for 38 yards on 17 carries. Far from his best game, but more than good enough. After a conservative start, he bounced off tacklers, scrambled away from pass rushes and generally looked like the guy Florida fans have grown to adore.

The LSU offense looked all too familiar, too. The Tigers came in ranked last in the SEC in total offense and managed only 162 yards. They never even threatened to score in the second half.
