Coming off what amounted to a 15-minute performance in its season opener, No. 23 UCLA hopes to put together a full 60-minute effort against Oklahoma State Saturday.
The Bruins (1-0) trailed then-No. 19 Colorado State 13-7 entering the fourth quarter in their season opener at the Rose Bowl Saturday before taking control.
Akil Harris and Manuel White ran for touchdowns 64 seconds apart early in the final quarter, and White scored an insurance TD with 1:01 remaining, as UCLA rallied for a 30-19 victory.
"For a young team to do that against a Top 20 team that's had two games already, I was really proud of our kids," UCLA coach Bob Toledo said. "We came out in the second half and did some nice things, we controlled the line of scrimmage."
The win was the Bruins' eighth in a row in the regular season against a nonconference opponent since a 42-20 loss to Ohio State on Sept. 11, 1999.
Much of UCLA's early struggles in the opener can be traced to quarterback Cory Paus, a fifth-year senior who was replaced by freshman Drew Olson for two series at the end of the third quarter and beginning of the fourth.
Olson guided the Bruins 52 yards on nine plays for the go-ahead score, capped by Harris' one-yard run with 9:52 to play.
Paus, bothered by an injured thumb most of last season, will be spelled by Olson again on Saturday, according to Toledo.
"Cory Paus is the quarterback, hopefully Cory can stay healthy," Toledo said. "There's no quarterback controversy, this was something we wanted to do for down the road. We'll do the same thing next week."
A difficult early season schedule continues for the Bruins on Sept. 21, as they play host to No. 18 Colorado. After visiting San Diego State the following Saturday, UCLA opens Pac-10 Conference play against Oregon State on Oct. 5.
Oklahoma State (1-1) rebounded from a season-opening loss to Louisiana Tech with a 45-10 rout of Division I-AA Northern Iowa Saturday.
Josh Fields threw two touchdown passes and ran for another score and Rashaun Woods caught nine passes for 175 yards.
Saturday will be the Cowboys' first game against a Pac-10 team since losing to Arizona State on Sept. 25, 1993.
"We have two good quarters each game," Woods said. "We are still trying to progress and turn it into four quarters. Once we get through it I think that we will be a good ball team. That's our goal right now, we just need to put four quarters together."
Woods is proving to be among the best receivers in the country. Dating back to the Cowboys' 22-19 loss to Colorado on Oct. 27, 2001, he has 47 receptions for 694 yards and eight TDs. That's a six-game average of 115.7 yards per game and 14.8 yards per catch.
