Youngster Thomas Laerke recorded 21 points for the Bakken Bears
Bakken Bears Aarhus upset the form book to record their first win in the Last 16 of the EuroChallenge and deny Ural Ekaterinburg the chance to book a quarter-final ticket on the night.
A huge third quarter guided the Bears to a 92-84 win as Kenneth Barker poured in 22 points and Thomas Laerke 21.
The Bears, who are already enjoying the longest EuroChallenge campaign in their history, outscored Ekaterinburg 25-10 in the third period, and a 9-0 run that stretched into the fourth quarter put them 68-52 up.
The Russians, knowing a win would send them through after Minsk won earlier in the day, did their best to rally, but the Bears kept finding an answer.
When Lance Harris made a three-point play from the line, Ekaterinburg had got it back to 76-70, but Afamefuna Okolie replied with a put-back from Barker's miss to pad the lead.
Fedor Kliuchnikov then nailed a three to make it a five-point game but after a time-out the Bears went on a critical 6-0 spurt to lead 84-73 on Chris Christofferson's dunk with the clock down to 1:53.
Anton Glazunov replied with another three only for Brandon Penn to reel off another six points, his dunk bookended by pairs of free throws, that effectively put the game out of sight for Ekaterinburg.
Penn finished with 15 points while Christofferson had 11 and Okolie 10.
Harris poured in 20 for Ekaterinburg with Aaron McGhee collecting 18 with 10 rebounds.
