McCoy threw for 259 yards and two touchdowns and Jamaal Charles scored on a 46-yard run Saturday to clinch the sixth-ranked Longhorns' 35-32 victory over Central Florida in the first game in the Golden Knights' new on-campus stadium.
Ryan Bailey kicked five field goals for Texas (3-0), which regrouped after squandering a 13-point lead to fall behind 24-23 early in the fourth quarter. Bailey put the Longhorns ahead for good, then tied a school record with a fifth field goal that made it 29-24 with 5:19 left.
Charles, who rushed for 153 yards on 22 carries, put the Longhorns up 35-24 with his long run after cornerback Marcus Griffin recovered a Central Florida fumble.
The Texas running back was trying to help the Longhorns kill the clock when he fumbled for the second time, giving Central Florida one more chance.
McCoy was 32 for 47 and was intercepted once. Quan Cosby had 10 receptions for 67 yards in the Longhorns' first appearance in the state of Florida in 34 years.
Kyle Isreal's 7-yard TD pass to Kamar Aiken and a 2-point conversion trimmed Central Florida's deficit to three with 35 seconds left. But Brandon Foster, who scored on a 33-yard interception return in the second quarter, recovered the ensuing onside kick to seal the victory.
Central Florida played its first 28 seasons in the Florida Citrus Bowl in downtown Orlando. The $55 million, 43,323-seat Bright House Networks Stadium was a long-range goal that coach George O'Leary put on a fast track after being hired in 2004.
The former Georgia Tech coach pulled off one of the biggest turnarounds in college football history two years ago, guiding the Golden Knights to the first bowl appearance in school history after going 0-11 in his first season.
