Colorado (3-2, 0-2 Pac-12) at Arizona State (1-4, 0-2). Either way, one of these teams will snap their losing streak in conference games. The Buffaloes have an eight-game losing streak in the Pac-12 where opponents have scored at least 42 points in each game. Colorado trailed USC by 27 points during the second half before its rally fell short in a 48-41 loss to the Trojans. The Sun Devils extended their losing streak to six in conference games and eight against Football Bowl Subdivision Opponents with last Saturday's 24-21 loss at California. Their last FBS win came last season at Colorado when Trenton Bourguet set a school record for most passing yards in a first career start with 435 along with three touchdowns. Buffaloes QB Shedeur Sanders is second in the nation in passing yards per game (356.2) and tied for fourth with 15 touchdowns.

No. 13 Washington State (4-0, 1-0) at UCLA (3-1, 0-1). This is their first meeting since the Bruins' wild 67-63 comeback victory in 2019. Both teams were off last week. Washington State's Cameron Ward is only the fifth QB since 1996 from a Power Five school to throw for at least 1,300 yards (1.394), 13 touchdowns and no interceptions in his team's first four games. UCLA's defense is holding teams to only 11 points per game while opponents have scored only 55.5% of the time on red zone trips.

It is the first time since 2013 the conference has had at least three teams reach 5-0 (Oregon, USC, Washington). Should Washington State win on Saturday, there would be four 5-0 teams for the first time since 1926. … Arizona WR Jacob Cowing is just 72 receiving yards away from reaching 4,000 for his career. He would be the 1st FBS receiver since Oklahoma State’s James Washington in 2017 to accomplish that. … USC is looking to start 6-0 for the second consecutive season for the first time since 2005. … No. 7 Washington, No. 8 Oregon, No. 18 Utah and Stanford are off next week.
