Maybe there will be a rematch.

If so, UCLA has some work to do.

UCLA became the first team this season to play No. 2-ranked Oregon to as much as a tie in the first half.

But it was all downhill after that.

The No. 12-ranked Bruins were shutout in the second half of a 42-14 loss to the Ducks at Autzen Stadium in Eugene, Ore.

And as UCLA stalled, Oregon got its offense very much in gear.

Quarterback Marcus Mariota completed all 10 of his second-half passes, and sophomore running back Byron Marshall turned in his fifth consecutive triple-digit rushing game, finishing with 133 yards and three touchdowns in 19 carries.

Mariota finished having completed 21 of 28 passes for 230 yards and a touchdown as Oregon improved to 8-0 overall, 5-0 in Pac-12 Conference play.

Marshall was a backup until De'Anthony Thomas injured his ankle. Thomas returned to action on Saturday, running for 31 yards in 10 carries, all in the first half. Thomas did not play in the second half.

Back of Marshall, Oregon showed it has yet another up and comer. Freshman Thomas Tyner ran for 77 yards in 14 carries. He had all 66 yards in an eight-play scoring drive in the fourth quarter.

Oregon finished with 325 yards rushing. UCLA had 219 yards rushing, including 93 in 22 carries by Paul Perkins and 72 and a touchdown in 15 carries by quarterback Brett Hundley.

However, Hundley suffered through a horrific passing game, throwing for just 64 yards in 13 completions in 19 passes. He had two passes intercepted.

The score might have been more lopsided if not for two Oregon mistakes.

The first, a fumble, set up UCLA's first touchdown. Later, UCLA freshman Myles Jack blocked a punt, setting up the Bruins' final touchdown.

UCLA fell to 5-2 overall, 2-2 in Pac-12 play.

The Bruins and Ducks could meet in a rematch in the Pac-12 championship game.

Oregon 42, UCLA 14 (2:25 left in fourth quarter)

If sophomore Bryon Marshall is the future (and present) of Oregon's running attack, then freshman Thomas Tyler is whatever is after that.

It all looks bright for the Ducks.
