BOULDER, Colo. -- Chris Ogbonnaya's sweet blend of speed and strength put Texas in the end zone and kept Colorado out.

Ogbonnaya scored two touchdowns and saved another in the fifth-ranked Longhorns' 38-14 rout of the Buffaloes on Saturday.

The oft-overlooked senior running back scored on a 65-yard dump-off and a 13-yard gallop through the befuddled Buffs' defense, then saved a score when he chased down cornerback Jalil Brown at the Texas 16 after a rare interception of former Jim Ned standout Colt McCoy, who was picked off twice.

Ogbonnaya's trio of tremendous plays helped the Longhorns (5-0, 1-0 Big 12) take a 21-0 halftime lead and assured there would be no peeking toward next weekend's Red River Rivalry showdown against top-ranked Oklahoma in Dallas.

Ogbonnaya (pronounced OH-bon-EYE-uh) finished with a career-best 71 yards on nine carries and caught six passes for 116 yards, just 4 yards shy of Eric Metcalf's 1985 school record for most yards receiving by a Texas running back.

McCoy completed 23 of 30 passes for 262 yards and two TDs.

Quarterback Cody Hawkins Hawkins completed just 13 of 33 passes for 118 yards in his second straight poor performance for Colorado (3-2, 0-1).
