text: A frozen corner at Stade Jean-Bouin meant the game began 95 minutes after the scheduled kick-off time.
  Waisea Nayacalevu and Julien Arias put the French side 17-5 up at the break with Mat Luamanu crossing for Quins.
  Craig Burden added a third Stade score before Marland Yarde and James Chisholm went over for late tries.
  Quins knew they had to win the game to progress to the quarter-finals but the home side went through instead, and will be away to Ospreys in the last eight.
  A corner of the pitch was still frozen at the scheduled 13:00 GMT start but play was able to start at 14:35.
