In what seems like an early "Rivalry Week," college football fans are in for a treat with a whopping 21 matchups pitting in-state schools and old-school border battles against each other in Week 3. This unexpected slate of heated rivalries promises to bring excitement, upsets, and intense competition before teams part ways into different conferences.

One of the highlights of the week is the clash between the Oregon Ducks and the Oregon State Beavers. This longstanding rivalry, with the Ducks leading the series 68-49-10, has been reignited as the Beavers seek redemption after being jilted by the Ducks' move to the Big Ten. With both teams holding a 2-0 record, the stage is set for an intense showdown at Reser Stadium in Corvallis.

Another bitter rivalry to watch is the Washington State Cougars taking on the Washington Huskies. With the Huskies leading the series 76-33-6, this Apple Cup matchup has been fueled by grievances as both teams remain undefeated so far. Though the game will be played at the Seahawks' stadium in Seattle instead of Pullman, the Cougars are expected to bring their passionate fans and fierce determination.

A clash between the Colorado Buffaloes and the Colorado State Rams is sure to ignite old snobbery and deep-rooted dislike. With the Buffaloes leading the series 68-22-2, last year's double-overtime victory by the Buffaloes has only intensified the rivalry. The arrival of head coach Deion Sanders has added an extra layer of glamour and anticipation to this matchup.

In another intriguing showdown, the Cincinnati Bearcats will face off against the Miami (Ohio) RedHawks in their 128th meeting. With the series currently tied at 60-60-7, this rivalry, dating back to 1888, gained renewed interest after the RedHawks secured their first victory in the series since 2005. Both teams will be looking to claim bragging rights in this historic matchup.

These are just a few of the many exciting rivalry games taking place this week. From the West Coast showdowns of the Utah Utes against the Utah State Aggies and the San Diego State Aztecs against the California Golden Bears, to the intense clashes on the East Coast between the West Virginia Mountaineers and the Pittsburgh Panthers, and the Maryland Terrapins and the Virginia Cavaliers, fans will be treated to non-stop action and fierce competition.

As college football enters this unexpected "Rivalry Week" filled with highly anticipated matchups, the stage is set for memorable moments, upsets, and rivalries that will reignite the passion of fans across the nation. So grab your jerseys, get ready to cheer, and buckle up for a thrilling week of college football showdowns.
