Boulder, CO (Sports Network) - Kevin Eberhart's 45-yard field goal as time expired lifted the Colorado Buffaloes to a huge 27-24 win over third-ranked Oklahoma at Folsom Field.

After erasing a 17-point deficit, Colorado stopped Oklahoma and a 31-yard punt return from Chase McBride gave the Buffaloes the ball at midfield with 2:41 to play.

After a one-yard loss, Cody Hawkins hit Kendrick Celestine for a 16-yard play and a one-yard run from Hugh Charles and a six-yard run for Demetrius Sumler set up Eberhart's field goal attempt.

As the time was running out, Eberhart booted the ball just inside the left upright and the Colorado fans came rushing onto the field.

Hawkins went 22-for-36 for 220 yards with two touchdowns and two interceptions for the Buffaloes (3-2, 1-0 Big 12), who snapped a five-game losing streak to Oklahoma.

Charles finished the game with 23 carries for 110 yards and a score and added five receptions for 48 yards while Tyson DeVree and Dusty Sprague each had touchdown receptions for Colorado, who have won their last two games.

"Our guys were where they needed to be," said Colorado coach Dan Hawkins. "All week I told them we were going to win this game. I've been doing this for 25 years and you know when your team is ready. I was really pleased when it looked like things were getting away from us and our guys just kept coming."

Sam Bradford went just 8-for-19 for 112 yards with a touchdown and two interceptions while Allen Patrick had 18 carries for 96 yards and two scores for the Sooners (4-1, 0-1), who travel to Texas next Saturday.

"It's never a shock when you're the one who is competing," said Oklahoma coach Bob Stoops. "We understood we needed to play well to win and we didn't. We made some really poor penalties and we didn't play very smart, we turned the ball over there late. You just can't have those things happen. The really poor, foolish things we did just killed us. We're not a very smart team right now."

Trailing, 24-7, the Buffaloes made it a 24-10 game with 4:10 left in the third quarter on a 41-yard field goal from Eberhart.

Ryan Walters picked off Bradford on Oklahoma's ensuing possession and Colorado took advantage of the turnover. A nine-play, 60-yard drive that spanned the third and fourth quarters was capped off when Hawkins found DeVree in the end zone from four yards out to cut the deficit to 24-17 just 10 seconds into the fourth.

Colorado had a chance to cut into its deficit when the team lined up for a 36- yard field goal, but Eberhart pushed it right.

However, Daniel Dykes picked off Bradford on the first play of Oklahoma's next possession, but Colorado was held and forced to punt.

Again turnovers plagued the Sooners as Reggie Smith fumbled the punt after fielding it and Justin Drescher fell on the ball to give the Buffaloes the ball at the Oklahoma 16. Three plays later Hawkins and Sprague hooked up on a 15-yard touchdown to tie the game with 4:05 to play.

The Sooners grabbed a 7-0 lead in the first quarter. D.J. Wolfe picked off a Hawkins pass and returned it to the Colorado 11 and three plays later Bradford found Juaquin Iglesias in the end zone with 1:40 left in the quarter.

The Buffaloes tied the game in the second as Charles took a handoff 25-yards into the end zone to cap an eight-play, 70-yard drive with 8:26 remaining until halftime.

However, Oklahoma took the lead into the locker room with a pair of scores.

On the ensuing possession, Bradford hooked up with Joe Jon Finley on a 43-yard catch and on the next play Patrick took the ball into the end zone from 34 yards out for a 14-7 lead.

After stopping Colorado on its next possession, Oklahoma drove the ball down the field and a 28-yard field goal from Garrett Hartley made it a 17-7 game.

In the third quarter, Wolfe again picked off Hawkins deep in Colorado territory and on the next play Patrick took the ball into the end zone for a 24-7 lead less than three minutes in.
