No. 5 Tennessee was blown out 63-38 by South Carolina in the biggest upset of the day. The Vols defense was helpless against the Gamecocks' prolific passing game.

That loss could potentially be great news for No. 7 USC, which held off UCLA 48-45 in a wild affair. That puts the Trojans at 10-1 with a spot in the Pac-12 title game secured. The Trojans' playoff hopes are very much alive.

Meanwhile, it was a scary day for another group of playoff hopefuls as No. 2 Ohio State, No. 3 Michigan and No. 4 TCU all had to survive some close calls on Saturday.

Ohio State held off a furious late rally from Maryland to win 43-30, Michigan beat Illinois 19-17 on a field goal with 9 seconds to play, and TCU prevailed 29-28 over Baylor on their own last-second field goal.

Even No. 1 Georgia had a less-than-convincing 16-6 victory over Kentucky. In the end, everyone got the job done to get up a high-stakes final weekend of the regular season.
