NORMAN, Okla. (AP) -- Allen Patrick didn't think he needed a pep talk from the record-setting running back he was replacing. He got one anyway.
After a brief encounter with Adrian Peterson right before kickoff, Patrick ran for 110 yards and a fourth-quarter touchdown to lead No. 20 Oklahoma to a 24-3 win Saturday night against Colorado.
"When I was going out there on the field, I just had my mind set to go out there and give punishment, to let them know I'm on the field, to let me go out there and get my name known," Patrick said. "I was going out there trying to make things happen."
Peterson, who broke his collarbone last week against Iowa State, watched the game from the sidelines in a gray hooded sweat shirt and red cap. After the coin toss, he and Patrick spoke near midfield.
"He pretty much knows I can run the ball. He was just telling me to go out and get it, just keep grinding until I get it," Patrick said. "I finally got it for him."
In his first start, Patrick surpassed his career-high for carries early in the third quarter and finished with 35 rushes - more than Peterson had in a game this season.
"It was different, but I was definitely satisfied with what Allen was doing out there," Sooners quarterback Paul Thompson said.
Oklahoma relied on Patrick from the start. He carried seven times for 36 yards on the Sooners' first scoring drive, setting up Thompson's 3-yard TD pass that Manuel Johnson caught with one foot inside the left edge of the end zone.
"He's coming back and he wants the ball more and more," Thompson said of Patrick. "Even though he hasn't been in that position and he's not a star, he definitely has a role of a leader of this offense, coming back to the huddle, telling guys, 'Come on, let's go! Keep it rolling.' He's going to be a big part of this offense."
Patrick got periodic advice from Peterson. The nation's No. 2 rusher and 2004 Heisman Trophy runner-up took part in Oklahoma huddles during timeouts and was almost always among the front row of Sooners on the sidelines.
Mainly, Patrick said, Peterson told him to run toward openings outside instead of continuously slamming the ball inside.
Patrick ended up as the first player to run for more than 100 yards this season against Colorado (1-7, 1-3 Big 12), which entered with the nation's No. 9 defense against the run.
"He has all the confidence in the world, and I have all the confidence in him," Thompson said. "He was making some plays for us."
Patrick got the ball on seven straight plays as Oklahoma ran out most of the final 6:13. He finally got a rest after converting a fourth-and-inches with 2 1/2 minutes left. Freshman Chris Brown took over and scored on a 4-yard run with 17 seconds remaining.
"Our focus is on this team. You're definitely aware that Adrian's not back there, but we're not down about that," Thompson said. "We're not looking to see if we can overcome that."
The Sooners (5-2, 2-1) got all four of their scores going with the wind, and coach Bob Stoops even called two timeouts to keep the wind at Oklahoma's back before Garrett Hartley 's 46-yard field goal made it 10-0 at the end of the first quarter.
"The conditions weren't the best," Stoops said. "The gusts of wind that were down there were really tough."
Colorado couldn't do much on offense, no matter which way the wind was blowing. The Buffaloes managed only two first downs on their first nine possessions, and Bernard Jackson didn't complete his second pass until the fourth quarter.
He finished 3-for-14 for 39 yards with one interception, and Colorado had a season-low 113 yards of total offense.
"I was not vocal enough. I'll take the blame for this game," said Jackson.
The Buffaloes avoided their first shutout in 18 years on Mason Crosby 's 39-yard field goal, a line drive into the wind, with 6:13 to play.
Crosby missed a 56-yard field-goal attempt wide left that would have pulled Colorado within 10-3 in the second quarter, and Zach Latimer intercepted a tipped pass by Jackson after the Buffaloes had taken possession in Oklahoma territory on Jordan Dizon's fumble recovery.
The loss ended any remaining bowl hopes for Colorado, which halted a 10-game losing streak with a win against Texas Tech last week. The Buffaloes are winless in their last 13 games against ranked opponents.
