PASADENA, Calif. -- Josh Rosen threw for 372 yards and one touchdown, Soso Jamabo and Jalen Starks each ran for a touchdown, and UCLA broke a two-game losing streak with a 27-23 win over Colorado on Saturday night.
The Bruins (3-2, 1-1 Pac-12) held off the Buffaloes (3-2, 0-2) with a late defensive stand. Steven Montez's final pass sailed out of the end zone three plays after finding Jay MacIntyre on a 31-yard completion to set up the Hail Mary try.
Montez passed for 243 yards and one touchdown and ran for 108 yards, as Colorado lost its fourth straight game at the Rose Bowl since joining the Pac-12 in 2011. Phillip Lindsay added 83 yards rushing and one touchdown and had four receptions for 47 yards with a touchdown.
Rosen mixed in his usual NFL-caliber throws and head-scratching decisions in his fifth-straight 350-yard game. He found Austin Roberts all alone in the corner of the end zone for a 12-yard touchdown pass and connected with Jordan Lasley for 46 yards on a flea-flicker, but also made a reckless throw into double coverage that was intercepted by safety Evan Worthington to set up the second of three 33-yard field goals by James Stefanou.
But when Colorado cut UCLA's lead to 24-23 with 6:46 remaining, Rosen went 4 of 6 for 54 yards to drive the Bruins into the red zone. Jamabo then ran for a first down on third-and-6, forcing Colorado to use its final timeout with 2:01 to go. JJ Molson kicked a 31-yard field goal with 26 seconds remaining to extend UCLA's lead, capping a drive that took 6 minutes, 13 seconds off the clock.
Colorado: The Buffaloes will need to go on a run to defend their Pac-12 South division title. Each of the last five representatives from the South to play in the Pac-12 title game went at least 6-3 in conference play, which likely means Colorado can absorb at most one more loss against a schedule that still includes road games at No. 16 Washington State and No. 20 Utah and a home game against No. 5 Southern California. Shoring up pass protection for Montez and finding consistency in the secondary will be requirements for that winning streak to happen.
UCLA: It wasn't a flawless performance, but the Bruins' embattled defense delivered. When they weren't committing unnecessary penalties to extend Colorado drives, UCLA actually played well. The worst run defense in the country entering the weekend was solid enough despite allowing 5.0 yards per carry, while the pass rush had Montez running around on nearly every drop back. Considering how explosive Rosen and the offense have looked, even an average defense should give UCLA a chance to win every game left on the schedule.
EJECTIONS ADDING UP
UCLA cornerback Darnay Holmes was ejected for targeting in the first quarter for a hit on Lindsay as the running back tried to catch a pass in the flat on third down. No flag was thrown on the field, but a subsequent video review disqualified the freshman for using the crown of his helmet to hit a defenseless receiver above the shoulder.
Lindsay caught a 21-yard touchdown pass from Montez on the next play.
Holmes became the fourth UCLA defender in as many games to be assessed a targeting penalty.
Colorado: The Buffaloes host Arizona next Saturday.
UCLA: The Bruins have a bye week before visiting Arizona on Oct. 14.
