Answer based on context:

Coach Coughlin's former team dominated the Giants in 2006, when he faced them for the first time. For this rematch, the Giants were without their two star receivers; Smith's pectoral injury caused him to miss his third game, while Nicks underwent treatment for compartment syndrome caused by a leg injury in Philadelphia. The Giants had signed Michael Clayton during the week to bolster their receiving situation, but he saw little action in this game. For the first three quarters, the Jaguars' defense held the Giants to three Tynes field goals; this was now the third straight game in which the Giants were held to 6 points or fewer in the first half. Rashad Jennings and David Garrard provided Jacksonville with two rushing touchdowns to take a 17-6 lead at halftime. The offense finally came to life at the end of the third quarter, when big plays by Jacobs and Boss set up a 26-yard Manningham touchdown reception followed by a two-point Bradshaw run. Later in the fourth quarter, Manning led the Giants down the field on a 6-play, 61-yard drive, culminating in a go-ahead 32-yard touchdown catch by Boss. The Jaguars threatened a comeback, and even made it into New York territory after the two-minute warning. But Justin Tuck, Antrel Rolle, Jason Pierre-Paul, and Terrell Thomas combined to sack Garrard on three consecutive plays, the last of which resulted in a fumble that was recovered by Rolle. The Giants had won their first turnover-free game of 2010, and tied the Eagles for the division lead.
