Four Power Five teams entered the weekend undefeated in conference play. But not all of them would endure Saturday’s challenges.

First, USC shocked No. 7 Michigan State with a 70-64 victory at home. This loss broke a 13-game winning streak for the Spartans, who had previously dominated their first nine Big Ten games.

The last loss for Michigan State occurred during the Maui Invitational semifinals back in November. They now sit with a record of 18-3 (9-1 Big Ten), competing closely with Purdue (17-5, 9-2), the only other Big Ten team boasting at least nine wins in conference play.

Moreover, Houston, ranked 6th, also faced defeat. This highly anticipated matchup saw Houston losing to No. 22 Texas Tech with a narrow score of 82-81 in overtime, marking the end of Houston’s 33-game home winning streak.

As a result of these upsets, Auburn and Duke remain the last two undefeated teams in their respective conferences.
