when DE Anthony Spencer forced a fumble from freshman RB Darius Walker that Purdue recovered. Orton then led the Purdue offense 97 yards on a drive that culminated in a short TD toss to DE-turned-TE Rob Ninkovich, for a 20–3 halftime lead. Early in the 3rd quarter, after a Notre Dame punt pinned Purdue at their 3-yard line, WR Taylor Stubblefield beat tight man coverage to catch a 97-yard TD pass for a backbreaking score and 27–3 lead. The teams exchanged touchdowns for the rest of the 3rd quarter before a scoreless 4th quarter.

Purdue gained an early 10–0 advantage with a 50-yard FG by Ben Jones followed by a short Brandon Jones TD run. The key play of the TD drive was a 55-yard completion to TE Charles Davis. But Senior QB Zack Mills, who had a fine day, led PSU back to tie the game at the half. First, they answered Purdue's TD drive with a TD of their own – a 37-yard TD pass to a diving WR Terrell Golden. Then, the Nittany Lions capped their next drive with a FG by K Robbie Gould. Purdue took a 17–10 lead on their first drive of the 2nd half with a 40-yard TD pass from Kyle Orton to Taylor Stubblefield.
