BOULDER, Colo. — Chucky Jeffery had 22 points and seven rebounds, and Arielle Roberson added 13 points as unranked Colorado stunned No. 8 Louisville 70-66 Friday night.
The crowd of 3,408 stormed the floor shortly after the final buzzer sounded.
Jen Reese added 11 points and sealed the win with a rebound basket for Colorado (9-0), which beat a top 10 team for the first time since defeating No. 2 Stanford in the round of 16 during the 2002 NCAA tournament.
The Buffaloes are 62-142 against ranked opponents. They are also off to a 9-0 start for the fourth time, and the second straight year.
Antonita Slaughter paced Louisville (9-2) with 19 points. Shawnta Dyer had 14 points for the Cardinals, who finished 3 for 19 from 3-point range and lost for the second time in three games.
The Cardinals trailed by six at halftime, but dug in defensively to hold Colorado scoreless for nearly 5 minutes at the start of the second half. Their offense couldn't take advantage, though, managing only two baskets by Dyer during that same stretch before Roberson sank two free throws to make it 38-34.
Dyer got Louisville as close as 41-40 with a rebound basket with 14:01 left, but the Cardinals couldn't get over the hump. Jeffery put Colorado ahead 48-43 with four straight free throws before Slaughter answered with a 3-pointer.
The Cardinals managed only a free throw by Jude Schimmel over the next 3 minutes as Colorado outscored Louisville 12-3 to build the lead to 60-51.
Slaughter closed the gap to 68-66 with a basket. Brittany Wilson missed both free throws with 11 seconds left, but Reese got the rebound off the second miss and put the ball back up to seal the win.
Outhustled and outrebounded 19-12, Louisville appeared stunned trailing 36-30 going into the break. Shelby Harper's two free throws put the Cardinals ahead 8 minutes into the game but Colorado came roaring back, with Jeffery and Lexy Kresl making 3-pointers to give the Buffaloes a 23-16 lead.
Jeffery scored on a baseline drive and a 3 to make it 30-22. Louisville got the deficit down to four points, the last time on Slaughter's two free throws before a layup by Rachel Hargis pushed Colorado's lead back to six at halftime.
The Buffaloes had a 10-2 scoring edge on second-chance points.
