For the first three and a half quarters in Miami today the Denver Broncos (2-4) couldn't score. For the final half-quarter and into overtime they couldn't be stopped. Tim Tebow led the Broncos to 15 fourth quarter points and a fieldgoal 2:44 into overtime to secure an 18-15 win over the Miami Dolphins (0-6) today.

Tebow made his first start of the year after Denver benched Kyle Orton, and for much of the game the Broncos sputtered. As Tebow walked to the sideline after one series stalled, spectators chanted his name in derision, and Dolphins players gestured to the crowd to keep the jeers coming.

But with the Broncos on the ropes, he led an eight-play touchdown drive that got them back in the game. Matthew Willis' 42-yard reception was the big gain, and Tebow threw a 5-yard scoring pass to Demaryius Thomas with 2:44 left to make the score 15-7.

Then came the onside kick. Miami receiver Marlon Moore leaped to catch the ball but bobbled it and the Broncos' Virgil Green recovered at their 44 with 2:31 left.

Tebow's strike to a diving Daniel Fells gained 28 yards to the 3. Two plays later, Tebow fooled the Dolphins by rolling left and throwing back to the right to Fells, who dived across the goal line for a 3-yard score with 17 seconds left.

Denver still needed a 2-point conversion to stay alive, and Tebow ran up the middle to send the game to overtime.
