Kyle Sinckler's suspect temperament cost Quins dear again as the London club's bid for a third European Challenge Cup success faltered at the Stade Marcel-Michelin.
The prop was instantly removed from the action eight minutes from the end after clearly upsetting boss Paul Gustard with his rash behaviour.
With his side fighting back and threatening to turn this contest around, Sinckler foolishly threw a Clermont player to the ground and straight at the feet of referee John Lacey who had to leap out the way.

It spoiled a spell of real strong Quins pressure where they had scored two fine tries through Chris Robshaw and James Laing, and were hoping for a grandstand finish.
