Colorado at Arizona (10:30 a.m. PT, FX) - The Wildcats might be heavy favorites in this game, but Colorado has fond memories of last year's matchup, as a 48-29 win over Arizona gave the Buffaloes their first-ever conference victory in the Pac-12. A lot is on the line for Arizona in this one - a win, and the Wildcats are bowl eligible in RichRod's first season as head honcho in the desert. Additionally, this is a good chance to see two good young ball-carriers go at it with freshman Buff Christian Powell and sophomore 'Cat Ka'Deem Carey.

Arizona State at No. 19 USC (12:00 p.m. PT, Pac-12 Networks) - All sorts of Pac-12 South implications abound in this one. With both teams very much alive in the division race, a win gives the victor a big step up in the race to play on Nov. 30, while the loser can start to hear the fat lady warm up her vocal chords. What also makes this game a must-win for both sides is that the teams are both on losing skids and need some positive momentum heading into the final couple of weeks. Arizona State defeated the Trojans 43-22 at home last year to snap an 11-game winning streak in the series for the Trojans. Time for a new streak for USC or a two-gamer and bowl eligibility for the Forks?

No. 11 Oregon State at No. 14 Stanford (12:00 p.m. PT, FOX) - Consider this a Pac-12 North elimination game, just about. The winner of this battle still controls their own destiny heading into the middle of November and owns the tiebreaker over the loser should it come to that. And, since only two teams from each conference can go to a BCS bowl game and a team needs to finish in the BCS top 14 to be considered for an at-large selection, the winner also gets a leg up on snagging a potential BCS bowl berth. Yeah, you could say this game has rather large implications. Stanford has won the last two in this series; a win over Oregon State at home in the 2010 regular season finale clinched a spot in the Orange Bowl for the Cardinal.

Utah at Washington (7:30 p.m. PT, Pac-12 Networks) - Both teams come into this one riding two-game winning streaks. Washington survived a brutal schedule over the first eight games of the season and has put itself in a position to improve upon last season's 7-6 finish, while Utah responded to a four-game losing streak with back-to-back 49-point performances at home against Cal and Washington State. The key stat to watch here - can Utah running back John White get to 100 yards rushing? If he does, you can pretty much declare the Utes the victor - Utah is 11-0 in games over the last two years when White rushes for at least 100 yards. When he doesn't, the Utes are 1-10, and that lone victory came in a game in which White did not play. So assuming he suits up (and there's no reason to think he won't), keep your eye on White.

No. 18 UCLA at Washington State (7:30 p.m. PT, ESPN2) - The Cougars just saw bowl eligibility slip through their fingers last weekend at Utah and will now try to take out their frustrations out on a UCLA squad that has the exact opposite record of Washington State overall.  That means UCLA is already bowl eligible and has already improved upon the 2011 season, but the Bruins need to keep winning to hold on to the top spot in the Pac-12 South. The Bruins and Cougars played a close one in the Rose Bowl last year, with UCLA coming out on top, 28-25. The loss was the first in a five-game losing streak for Washington State, which has also lost four straight to the Bruins.

No. 3 Oregon at Cal (7:30 p.m. PT, ESPN) - A lot of people are saying the 2012 Oregon Ducks are better than the 2010 Oregon Ducks, a team that barely received a threat in the regular season en route to a Pac-10 championship and appearance in the BCS national championship game. The one scare that 2010 team did get, though, came at Cal, a game the Ducks held on to win by just two points. And while Cal has been a very good team over the years under Jeff Tedford, that 2010 Golden Bear team was the first time in his tenure that Cal finished with a losing record. So just because the Golden Bears won't go bowling this year doesn't mean the Ducks can take them lightly, especially at Memorial Stadium.
