The second "Manning Bowl" was only the second time in NFL history that two brothers started opposite each other at quarterback, in a game which was expected to be an offensive struggle between Eli and his older brother Peyton. But the Giants didn't seem to have an answer for Peyton or the Colts' running game, which was led by Joseph Addai and Donald Brown. The Giants were shut out at the half for the third time in their last four games (dating back to last year) after the Colts scored the first 24 points of the night. Brown recorded a 7-yard scoring run, and Dallas Clark and Austin Collie caught touchdown passes of 50 and 3 yards, respectively. The Colts defense held the Giants to 75 yards of offense in the first half, including just 17 passing yards for Eli. The Giants finally got on the board on the first drive of the second half, when Eli connected with Mario Manningham for a 54-yard strike. But on the Giants' next drive, an Eli fumble was picked up in the end zone by Fili Moala, effectively taking the Giants out of the game. Two additional scores occurred in the fourth quarter; Peyton connected with Reggie Wayne for a 10-yard score, and Eli threw a 31-yard touchdown to Week 1 star Nicks. On a night when almost nothing went right for the Giants, Brandon Jacobs caused a stir by throwing his helmet into the stands in the third quarter, which he later claimed was a botched expression of frustration. The NFL fined Jacobs $10,000 for the incident.
