Courtney Paris was her usual self.
Amanda Thompson had an all-around spectacular game.
But none of it was good enough to offset Charel Allen and the Notre Dame Fighting Irish on Tuesday night.
Allen scored a career-high 35 points and all the clutch plays necessary to help Notre Dame upset Oklahoma 79-75 in the second round of the NCAA Women's Basketball Championship at Mackey Arena in West Lafayette, Ind.
Oklahoma's season ends at 22-9 and short of the Sweet 16 for the first time in three years. The Sooners lost four of their last five games.
Oklahoma led by seven points with eight minutes to play, but gave a up a 16-4 run and found itself trailing 65-60 with 2:02 left in regulation. Allen scored 10 of Notre Dame's points during the run.
The Sooners fought back, however, and tied the game when Paris worked her way into the paint for a bucket with 13.7 seconds remaining.
Allen had a chance to win it for Notre Dame in regulation, and almost did, but her shot bounced on the rim three times before falling off.
Oklahoma quickly took a five-point lead in overtime, but Allen knocked down a 3-pointer and grabbed a steal that led to the game-tying layup just seconds later.
Oklahoma took the lead back, 72-70, on an Ashley Paris bucket with 2:08 to play, but Notre Dame closed the contest on a 9-3 run.
Allen and Ashley Barlow each made a pair of free throws in the final 11 seconds to help preserve the win. Allen was 12-of-12 from the line and 3-for-3 from the 3-point line.
It helped offset Courtney Paris, who recorded her 92nd consecutive double-double with 24 points and 16 rebounds. Paris was held scoreless for nearly 12 minutes to start the contest.
Thompson added 19 points, eight rebounds and a team-high eight assists for the Sooners. Plumley, who has been inconsistent all season from beyond the arc, was 6-of-10 from long range Tuesday for all 18 of her points.
Overall, Oklahoma shot 56.3 percent (9-of-16) from beyond the arc and out-rebounded Notre Dame 34-22. That number included 15 offensive boards for the Sooners, seven by Courtney Paris.
However, Notre Dame did its handiwork at the foul line, knocking down 22-of-24 attempts. Oklahoma was just 6-of-9 from the stripe. Thompson and Danielle Robinson each fouled out in the contest.
