An end-zone celebration went embarrassingly wrong Saturday for an Iowa cheerleader who lost his pants.

The cheerleader executed some backflips in the end zone before his pants fell to his ankles. Like a seasoned quarterback, the cheerleader kept his composure and promptly righted the situation.

If there was a negative on the day that was it.

Cade McNamara threw for two touchdowns and freshman Kamari Moulton scored twice after halftime in his debut, helping No. 25 Iowa beat Western Michigan 41-10 on Saturday.

Leshon Williams rushed for a career-high 145 yards on 12 carries as the Hawkeyes (3-0) pulled away in the second half of a game delayed 42 minutes by lightning in the first quarter.

Iowa, which led just 14-10 at halftime, had a season-high 387 total yards.

McNamara, who was 9 of 19 for 103 yards and two interceptions, threw a 3-yard touchdown pass to Diante Vines in the second quarter and a 25-yard scoring toss to Williams in the third quarter.
