On the game's first possession, Chad Pennington was sacked by Robert Mathis, fumbled, and the Colts' Josh Thomas recovered. Dominic Rhodes would score on a 6-yard touchdown run minutes later, an inauspicious start. The teams would trade punts for the rest of the first quarter before Pennington drove the Jets at the beginning of the second quarter, using long completions to Laveranues Coles and Tim Dwight before he found Jerricho Cotchery on a 33-yard touchdown pass. What happened next stunned the Colts: Mike Nugent tried an onside kick and Kerry Rhodes recovered, sparking the home crowd. The Jets would make that surprise work, as Kevan Barlow scored on a 1-yard touchdown run with 4:44 left in the first half, and the Jets had a 14-7 lead. But Peyton Manning rallied the Colts, converting a key third down to Marvin Harrison before Joseph Addai scored on a 2-yard touchdown run to tie the score going to halftime. Indianapolis punted to open the second half, and the Jets began to drive. Pennington converted three third downs on a drive that took nearly nine minutes off the clock, but it did not end well. Jets coach Eric Mangini tried his second gamble of the game: going for it on 4th-and-goal from the Colts' 2-yard line. But Pennington's pass was intercepted in the end zone by Rocky Boiman, the first time in his career Pennington was intercepted in the end zone. Boiman's interception would set up a fast-and-furious finish as the teams scored 31 points in the fourth quarter. Indianapolis took advantage of Boiman's interception and drove to set up Martin Gramatica's 20-yard field goal, as Joseph Addai picked up big yardage on the drive. Using a no-huddle offense, Pennington drove the Jets downfield, and aided by an illegal contact penalty on the Colts' Mike Doss, scored the go-ahead touchdown as Kevan Barlow scored on a 5-yard run with 7:55 to play. Manning led the Colts right back, and aided by a questionable pass-interference penalty on Justin Miller, found Bryan Fletcher on a 2-yard touchdown pass with 2:40 to play. Miller appeared to be the goat, but on the ensuing kickoff ran the ball back 103 yards for a touchdown that sent Jets fans into hysteria. The Jets led 28-24 with 2:20 to play. But that would be enough time for Manning, converting a huge third down to Marvin Harrison and a 15-yard pass to Reggie Wayne going to the Jets' 1-yard line. Manning ran the ball up the middle on the next play to give the Colts the lead. With eight seconds to play and the ball on the Jets' 32-yard line, Pennington completed a seemingly innocuous pass to Leon Washington. But what followed was an amazing attempt to pull off a miracle. In order, the Jets tried a series of several laterals, going from Washington, to Brad Smith, to Laveranues Coles, to Pennington, to Justin McCareins, back to Smith, who fumbled but recovered. He lateraled back to Coles, who fumbled but recovered. At this point, the Jets were at the Colts' 40-yard line. Coles ran down 13 yards and then tossed off to Nick Mangold, who fumbled, but this time, the Colts' Jason David recovered, ending the game.
