Munster were eliminated from the European Rugby Champions Cup on Saturday as Stade Francais overcame the first-half dismissal of Josaia Raisque to claim a crucial 27-7 victory at Stade Jean Bouin.
Raisque was sent off by referee Nigel Owens on the stroke of the interval, after making contact with the eye of Munster forward CJ Stander.
Yet Stade, who led 10-0 at the time, were still able to forge further ahead in the second half, despite their numerical disadvantage.
Paul Williams' first-half try was added to by scores from Sekou Macalou and Hugo Bonneval, with Morne Steyn contributing 12 points from the tee.
Conor Murray claimed a late consolation try for Munster, but the two-time European champions can no longer qualify from Pool Four.
Stade are now four points behind leaders Leicester Tigers, having triumphed in a fixture that was rescheduled as a result of November's terror attacks in Paris.
Racing 92, another club from the French capital, also played their game in hand on Saturday and moved to the brink of qualification from Pool Three with a 34-10 win over Glasgow Warriors.
Lock Manuel Carriza crossed for his side's fourth try to secure a bonus point with 80 minutes up on the clock.
Each of Racing's first three tries were scored by front-row forwards - Ben Tameifuna, Dimitri Szarzewski and Eddy Ben Arous all crossing - while Dan Carter kicked five goals from as many attempts.
Racing hold a seven-point lead over nearest rivals Northampton Saints, while Glasgow must win their remaining pool matches to have any chance of progressing.
