Welcome back, UCLA. Goodbye, Stanford.

Oregon headlines the list of six Pac-12 teams ranked in this week's AP poll, which does not include the Cardinal for the first time since the second week of the 2010 season. The Cardinal's school-record, 72-week run ended following a 26-10 loss to Arizona State on Saturday, which also propelled the Sun Devils to No. 14.

Oregon jumped Baylor, Michigan State and Notre Dame to No. 6 and is the nation's No. 3-ranked one-loss team behind No. 4 Alabama and No. 5 Auburn.

Arizona, which was idle this week, is a spot behind its in-state rival at No. 15.

The most anticipated game in the Pac-12 this week will be No. 20 USC's trip to No. 19 Utah, which is one of just two games in the country that will feature a pair of ranked teams.

After a 36-34 win against Cal, UCLA re-enters the poll at No. 25. The preseason No. 7 team was unranked last week after consecutive losses to Utah and Oregon.
