No. 7 Colorado 49, Iowa St. 42
BOULDER, Colo. (AP) _ Koy Detmer passed for 401 yards and five touchdowns, and Herchell Troutman ran for the tying and go-ahead touchdowns in the second half, helping No. 7 Colorado rally for a 49-42 win over Iowa State on Saturday.
The Buffaloes (8-1, 6-0 Big 12), trailing 28-21 midway through the third quarter, scored four touchdowns in a span of 13:55 for a seemingly comfortable 49-28 lead.
Rae Carruth caught three of Detmer’s scoring tosses, and freshman tight end Brody Heffner grabbed the other two.
The Buffs capped their flurry with 5:54 left, converting an interception by safety Steve Rosga into a 42-yard scoring pass from Detmer to Carruth. Detmer completed 27-of-47 passes and tied a school record with his five TD throws.
But Iowa State (2-7, 1-5) wouldn’t quit. Led by running back Troy Davis, who rushed for 228 yards on 35 carries, the Cyclones went 73 yards for a touchdown with 2:24 left. The Cyclones then recovered a Colorado fumble, and quarterback Todd Doxzon ran 4 yards on a quarterback draw with 28 seconds to go.
Colorado recovered the ensuing onside kick, however, and ran out the clock.
Davis boosted his rushing total to 1,822, putting him within range of becoming the first back in NCAA history to rush for 2,000 in two seasons. The Cyclones have two games remaining.
Colorado, extending its winning streak over Iowa State to 13 games, took a 21-13 halftime lead on three TD passes by Detmer.
But Iowa State scored twice early in the third quarter, once following a Colorado turnover, to take a 28-21 lead.
The Cyclones drew within 21-20 with a 65-yard scoring drive to open the second half. Davis carried four times for 50 yards on the drive, and Doxzon passed 17 yards to Tyrone Watley for the TD.
Moments later, Detmer fumbled when sacked by linebacker Derrik Clark at the Colorado 25, but Iowa State suffered two false starts and a sack and had to punt.
Colorado turned it over again, however, when Dawan Anderson intercepted Detmer’s pass and returned it 25 yards to the Colorado 8. Davis’ 1-yard run and Doxzon’s 2-point conversion pass to Watley put the Cyclones up 28-21. Colorado had only 10 players on the field for the conversion, and Doxzon found the open receiver.
Less than three minutes later, Colorado countered with a tying touchdown. Troutman broke loose on a 41-yard run and then took a pitchout 1 yard with 4:49 left in the quarter.
Later in the period, cornerback Toray Davis picked off Doxzon’s pass and returned it 22 yards to the Iowa State 43. Troutman’s 4-yard run made it 35-28 with 13:01 remaining.
The Buffs then went 65 yards in six plays, capped by Detmer’s 25-yard TD pass to the wide-open Heffner, for a 42-28 lead.
