The Arizona-Arizona State rivalry is one of the oldest in college football, dating back to 1899, with the Territorial Cup officially recognized by the NCAA as the oldest rivalry trophy in the game.
Nearly always played as the last regular season game for both teams, the contest between the Wildcats and Sun Devils splits the Grand Canyon State in half in terms of allegiances, usually around the time friends and family are gathering to celebrate Thanksgiving.
This year's edition is set for Saturday, Nov. 30, in Tempe, with ASU (9-2, 7-1) needing a win to be able to host the Pac-12 Conference championship against Stanford. The Sun Devils clinched the South Division title last week with a win at UCLA.
Arizona (7-4, 4-4) is looking to improve its bowl resume with an eighth victory, matching its total from 2012.
This will mark just the 11th time both teams will enter the game with winning records since both joined the Pac-10 in the late 1970s, making Saturday's battle for the Territorial Cup likely to provide some memorable happenings.
