Joe Marler waits on disciplinary action after appearing to kick opponent in the head

Joe Marler will face an anxious wait to see whether he will be hit with another disciplinary hearing after appearing to kick Grenoble hooker Arnaud Heguy in the head.

Harlequins romped past Grenoble 30-6 at The Stoop on Friday night to reach the European Challenge Cup final, but that three-try win was overshadowed by England prop Marler.
