London Welsh have suffered their second defeat of this season's Amlin Challenge Cup with a 20-9 loss to Grenoble in France.
The home side took an early lead through Vincent Campo's penalty, but two kicks from Alex Davies temporarily put Welsh ahead.
However, a second penalty from Campo made sure that the two teams went in level at the break.
Davies kicked over again eight minutes into the second half before Grenoble landed a significant blow when Clement Darbo converted Campo's try moments later.
The result was put beyond doubt with three minutes left as James Hart added the extras to Andrew Farley's score.
