London Welsh are still looking for an Aviva Premiership victory this season after Harlequins came from behind to win 24-13 at the Kassam Stadium.

Marland Yarde's try moments before the break proved to be the turning point of a match which the Exiles had led after opening the scoring on 20 minutes.

Will Robinson converted after Paul Rowley had crossed the line and then replied to Karl Dickson's try for Quins to help the Dragons into a 10-5 advantage.

However, England winger Yarde touched down following a swift burst on 37 minutes, with Tim Swiel adding the extras to put the visitors in front for the first time.

Second-half tries from Kyle Sinckler and Tom Williams put the Dragons, who could only find a Robinson penalty in response, out of sight as Quins even prevented Welsh from picking up a bonus point.

The Exiles remain bottom of the table with one point from 12 matches, while Quins climb to eighth.
