BOULDER, Colo. (AP) _ Koy Detmer passed for a school-record 426 yards and four touchdowns Saturday as ninth-ranked Colorado swarmed outmanned Northeast Louisiana 66-14.

Detmer, who broke his own record of 418 yards set against Oklahoma in 1992, played less than a minute into the third quarter. He had 352 yards and three touchdowns at halftime and Colorado had a 49-7 lead. But coach Rick Neuheisel left him in the game when the second half began because the record was in sight.

The junior quarterback needed only 57 seconds.

After two running plays, Detmer threw a 43-yard pass to tailback Herschel Troutman, then completed an 80-yard scoring drive with a 31-yard TD toss to Phil Savoy. His four touchdown passes tied a school record.

His final pass gave the Buffaloes a 56-7 lead over the Indians, a former Division I-AA powerhouse that moved up to Division I-A last year.

The game was an apparent warmup for Detmer and his Buffs for next week's game with third-ranked Texas A&M.

Troutman, a sophomore, scored three touchdowns before he left with an ankle sprain shortly after Detmer was pulled. Marlon Barnes, a sophomore who shares playing time with Troutman, scored twice, on a 40-yard run in the first quarter and a 2-yard run in the second.

The Buffs scored four touchdowns in the first quarter and ran the score to 35-0 early in the second period on Detmer's 11-yard scoring toss to Troutman.

Troutman had scored the Buffs' first TD on a 3-yard run and followed it less than a minute later with a 9-yard scoring run after Colorado recovered a Northeast Louisiana fumble on the Indians 30.

Detmer, brother of 1990 Heisman Trophy winner Ty Detmer, then connected with Rae Carruth for a 72-yard touchdown and the Buffs were on their way.

Detmer threw a 13-yard touchdown pass to Chris Anderson with 12 seconds to go in the half.

Northeast Louisiana (1-2) had closed the margin to 35-7 on a 23-yard run by Kendall Bussey in the second period, and to 56-14 on Carson Fields' 6-yard run early in the third.

Oddly enough, Colorado's first possession ended when Alonzo Hampton intercepted Detmer's pass in the end zone. Detmer had thrown 59 passes without an interception before that one.

The 66 points scored by Colorado also was a record, besting the 65 points the Buffs scored against Arizona in 1958.
