TEMPE, Ariz. — Malo Taumua blocked a field goal to lift UNLV to a 23-20 overtime upset of No. 15 Arizona State on Saturday night.

Taumua's block on a 35-yard field goal attempt by Thomas Weber came after Kyle Watson kicked a 20-yard field goal on the Rebels' overtime possession.

The loss took the luster off Arizona State's game against No. 2 Georgia next week.

For the Rebels, it will go down as one of the great victories in the school's sometimes checkered football history.

UNLV (2-1) tied it at 20 with 18 seconds left on Omar Clayton's 8-yard touchdown pass to Phillip Payne, who made a leaping one-handed grab.

The spectacular play capped a 10-play, 74-yard drive that lasted 2:45, with Clayton 6-of-8 passes for 70 yards.

For the Sun Devils (2-1), this was supposed to be a tuneup for next week's long-awaited game against No. 2 Georgia. But they let the Rebels hang around for too long.

Arizona State looked safe when Rudy Carpenter hit Kyle Williams for a 49-yard touchdown pass to put ASU ahead 20-10 early in the third quarter.

The Rebels served notice that they weren't going to be pushovers late in the second quarter. Carpenter threw an interception to UNLV defensive back Beau Orth, who returned it 9 yards to Arizona State 7.

Three plays later, Clayton threw a 2-yard touchdown pass to Payne, who outleaped cornerback Omar Bolden in the end zone with 33 seconds to play.

The Sun Devils responded with a quick four-play, 33-yard drive capped by Weber's 49-yard field goal as time expired in the first half, giving ASU a 13-10 halftime lead. The Rebels tied it at 3-3 on a 44-yard field goal by Watson midway through the second quarter.

Clayton completed 19-of-31 passes for 191 yards and two touchdowns for UNLV, which plays host to Iowa State next week. Carpenter finished 13-of-23 for 242 yards and two touchdowns, and he was intercepted once.

TCU 31, STANFORD 14: At Fort Worth, Texas, Ryan Christian scored the go-ahead touchdown and Steven Coleman made a key interception to help TCU beat Stanford in a game moved up six hours because of Hurricane Ike.

NEW MEXICO 36, ARIZONA 28: At Albuquerque, N.M., Rodney Ferguson ran for 158 yards and two TDs and freshman James Aho tied a school record with five field goals to help New Mexico beat Arizona.

AIR FORCE 31, HOUSTON 28: At Dallas, Air Force's offense couldn't have been better suited to play in the wind and rain brought by the edge of Hurricane Ike.

The Falcons ran the ball 71 times, didn't complete a pass, and Air Force withstood a late Houston rally for a win in a game moved to Dallas because of the hurricane.

WYOMING 16, NORTH DAKOTA STATE 13: At Laramie, Wyo., having not scored a touchdown in six quarters and down 10-0 to a lower division team, the Wyoming offense went back to the basic power running game.
