Context: The Colts traveled to The Meadowlands for a showdown with the New York Jets. This would be the second time this season that the Colts played at Giants Stadium, as they played the New York Giants in the regular season opener. Indianapolis scored first on a 6-yard touchdown run by running back Dominic Rhodes. The second quarter, though, was taken over by the Jets as they tied the game on QB Chad Pennington's 33-yard touchdown pass to WR Jerricho Cotchery, and took the lead on RB Kevan Barlow's 1-yard touchdown run. The Colts tied the game just before halftime on a 2-yard touchdown run by rookie RB Joseph Addai. After a scoreless third quarter, kicker Martin Gramatica, filling in for the injured Adam Vinatieri, made a 20-yard field goal early in the fourth to give Indianapolis the lead, 17-14. But New York regained the lead, scoring on a Kevan Barlow 5-yard touchdown score. Colts QB Peyton Manning rallied the Colts on their next possession, leading them on a scoring drive that led to a 2-yard touchdown pass to TE Bryan Fletcher. Illustrating perfectly the back-and-forth nature of the contest, the lead changed hands once again as DB Justin Miller returned the ensuing kickoff 103 yards for a touchdown to quickly move all the momentum to New York's side. But Indianapolis took the setback in stride as Manning methodically marched the Colts up the field and scored the game's final points on a 1-yard quarterback sneak. Facing a long field and with only eight seconds on the clock, on the game's last play Chad Pennington completed a pass up the middle to RB Leon Washington, who lateraled the ball to wide receiver Brad Smith in a desperate attempt to score a touchdown reminiscent of "The Play" between Stanford University and the University of California. Five laterals and three fumbles later, the Colts ended any hope of a Jets miracle comeback by recovering the final fumble of the play as time expired. Quarterback Peyton Manning finished the game 21 of 30 for 217 passing yards and one touchdown, Chad Pennington was 17 of 23 for 207 yards passing and had one touchdown pass and one interception. Manning was sacked twice while Pennington was sacked three times. Colts rookie running back Joseph Addai had a career-high 84 yards rushing as the Colts improved their record to 4-0.
