WEST LAFAYETTE, Ind. (AP) – Iowa spotted Purdue a 10-0 lead, then dominated the final 49 minutes, rallying for a 24-10 Big Ten opening victory Saturday.

The Hawkeyes (4-1, 1-0) took a 17-10 lead with 45 seconds remaining in the third quarter on a 23-yard touchdown pass from C.J. Beathard to Kevonte Martin-Manley, capping a six-play, 71-yard drive.

Officials first ruled that Martin-Manley caught the ball out of bounds, but after video review, it was clear the receiver caught the ball with one foot in bounds.

While Purdue (2-3, 0-1) struggled to generate any sustained offense after the first quarter, Beathard and running back Mark Weismann helped Iowa maintain possession.

Purdue, which is 0-9 in Big Ten play for second-year coach Darrell Hazell, scored first when strong safety Frankie Williams intercepted Beathard in the right flat and ran 39 yards for a touchdown with 4:13 to go in the first quarter.
