The Civil War rivalry heads south on Thursday when Pac-12 regular-season champion and tournament top seed Oregon faces eighth-seeded Oregon State in the conference tournament at Las Vegas.

Oregon State (18-13) advanced to the quarterfinal matchup against Oregon (24-7), the 13th-ranked team in the nation, with a 71-69 defeat of Utah in a first-round game Wednesday. Jarod Lucas hit a corner 3-pointer with 1.8 seconds remaining that sealed the win.

Oregon State's Tres Tinkle said after the game that the play was designed to go to Ethan Thompson, but that one of the Utah defenders played Thompson tight and kept the ball out of his hands.
