Video: Harlequins Try Ruled Out For This Questionable Knock-On

With Leinster leading 11-0 at half time it seemed that Harlequins had hit back immediately after the restart when Mike Brown went over for a great try.

However referee Romain Poite went upstairs to check on a possible knock-on in the build-up. Leinster argued that Joe Marler had knocked it on, Quins argued that Rob Kearney had ripped the ball from his hands.

The video ref sided with Leinster but not everyone was convinced.

Hell of a trick from the Harlequins player to spin the ball towards himself while apparently knocking it on

ruled to be a knock-on, I don't agree but Leinster escape
