England prop Joe Marler pretended to fight his own player after Harlequins scored a try against Clermont in the Champions Cup on Saturday.
Marler pulled the jersey of try-scorer Alex Dombrandt over his head and started throwing fake punches to his ribs.
Dombrandt reacted by kicking Marler on the ground which sent commentator Ugo Monye into hysterics.
Despite this try, Harlequins went on to lose the game 19-26 which has ended their Champions Cup campaign.
