Answer based on context:

The Indianapolis Colts home opener had their 2011 home opener against the 0-1 Cleveland Browns. The first quarter saw both teams getting into offensive and defensive rhythms and ended with the Colts holding only a 3-0 lead on an Adam Vinatieri field goal. Heading to the second quarter, the Colts offense began to pick up behind Kerry Collins, rookie Delone Carter, and Joseph Addai. However much of the success faded once Indianapolis reached the red zone, and were only able to come away with two field goals during the quarter. Cleveland, however, was able to capitalize on the Colts defense, and saw a touchdown pass from Colt McCoy and a touchdown run from Peyton Hillis. Cleveland went into halftime with a 14-9 lead. The Indianapolis defense was able to stop Cleveland for most of the third quarter, and allowed the struggling offensive to close the gap with a fourth Vinatieri field goal, with Cleveland still holding a 14-12 lead into the fourth quarter. Cleveland quickly drove down the field and started the quarter with a Phil Dawson field goal, allowing the Colts to remain in contention for the victory. However, after turnovers and an inability to produce on offense, Cleveland broke the game open with a Hillis touchdown run, along with another Dawson field goal with 2:59 remaining in the game. With Cleveland holding a 27-12 lead, Indianapolis was able to score their first touchdown of the game, allowing them to try an onside kick to preserve any chance of a comeback, which they were not able to convert. Cleveland finished the game and the Colts by winning 27-19, their first victory over the Colts since 1994, and the Colts first 0-2 start since the 1998 season.
