Mark Weisman led a punishing ground game with 145 yards on 35 carries as Iowa (2-1) ended Iowa State's run of two straight wins in the series. Kevonte Martin-Manley had seven catches for 60 yards and a score for the Hawkeyes, who controlled the ball for over 38 minutes.

Iowa State quarterback Sam Richardson threw three scoring passes to Quenton Bundrage, including two in a span of 2:01 to cut the deficit to 27-21 with 2:26 to play. Richardson finished 21-for-38 with three TDs and two interceptions and Bundrage had six catches for 141 yards.

Rudock, who completed 14-of-23 for 160 yards and two scores, directed a pair of long scoring drives after Richardson's first scoring strike to Bundrage, a 67-yarder that brought the Cyclones (0-2) within 13-7 with 5:28 left in the third quarter.

Rudock capped a nine-play, 60-yard march with a 26-yard pass to Jacob Hillyer to stretch the lead to 20-7 in the final minute of the third. Iowa extended the advantage to 27-7 midway through the fourth when Rudock plunged in from the 1 to finish a 15-play drive that ate up more than 7 1/2 minutes and featured 14 runs - eight by Weisman.
