The Badgers (3-1, 6-2) picked up ten points in the fourth quarter, tying the game with just less than three minutes to go, when Jim Leonhard returned a punt 63 yards for a touchdown.
Purdue, though, countered with an 11-play, 82-yard drive that culminated with Ben Jones hitting a game-winning three-yard field goal with just three seconds remaining.
Wisconsin quarterback Matt Schabert's Hail Mary pass attempt from the Wisconsin eight-yard line was tipped to the ground at midfield for the final play of the game.
Wisconsin quarterback Jim Sorgi turned the ball over on the Badgers' first two possessions, resulting in two Purdue touchdowns and an early 14-0 lead, quieting a rowdy Homecoming crowd at Camp Randall.
Had it not been for an early defensive score and the late special teams score, the Badgers loss to Purdue could have been even worse as the Badger offense never really got on track. It did not help that the Badgers lost three fumbles in addition to Boilermaker cornerback Jacques Reeves' interception on the game's first play.
The Kyle Orton show began on the Boilermaker 41-yard line. In the supporting cast were wide receivers Taylor Stubblefield and John Standeford. Orton completed his first five passes on a seven-play drive capped by a two-yard touchdown run by Jerod Void.
The second Badger drive ended on the Purdue 30 when Sorgi fumbled and Bernard Pollard recovered the ball. Nine plays later, Orton completed his sixth pass of the drive to Stubblefield for the six-yard touchdown reception and the Boilermakers' two touchdown lead.
Wisconsin pulled within seven less than two minutes later. Anthony Davis finished the 62-yard drive with a 28-yard touchdown run.
On the opening drive of the second quarter the Boilermakers were on the move again. The Boilermakers had moved from their own 22 to the Wisconsin 37 when the first of Alex Lewis' five sacks resulted in an Orton fumble. Linebacker Jeff Mack picked the ball out of the air and rambled for a 55-yard touchdown. Mike Allen's kick, though, went wide and the Badgers still trailed, 14-13.
Purdue added a field goal for the 17-13 halftime lead. It was a first half the Boilermakers dominated on the clock and in every statistical category. Purdue picked up 216 of their 411 passing yards in the first half. Orton was 26 for 31 in passing in the half including completing his first 15 attempts. He finished the game with 38 completions out of 55 attempts.
The Boilermakers converted their first possession of the second half to a field goal and a 20-13 lead.
The two turnovers were just the beginning of a bad day for Sorgi, who left the game at 8:44 of the third quarter with a knee injury. For the second week in a row, backup quarterback Matt Schabert came on in relief.
