Stade Francais sealed the last place in the quarter-finals of the European Challenge Cup at the expense of Harlequins with a 27-17 victory over last year's runners-up on Sunday.
Needing a win to leapfrop Quins into second place in Pool 5 and advance as one of the three best runners-up, the Top 14 side took charge in the first half and led 17-5 at the break after the start was delayed by over an hour and a half due to a frozen pitch.
Man-of-the-match Waisea Vuidarvuwalu and Julien Arias went over before the interval for Stade, with Mat Luamanu's try on the stroke of half-time giving Quins hope.
Craig Burden added a third try for the home side, with Jules Plisson contributing 12 points with the boot to put them 27-5 up and ensure scores from Marland Yarde and James Chisholm were in vain.
Stade will travel to Ospreys, who on Saturday became the only side to secure bonus-point wins in all of their pool matches, in the last eight.
Bath will host Brive, La Rochelle travel to Edinburgh and Gloucester entertain Cardiff Blues in the other quarter-finals.
