VIDEO: England’s Joe Marler under investigation for alleged racial slur during Wales game

England may be Six Nations champions, but they didn't make many friends on their way to victory.

Scotland's win against France on Sunday handed England the Six Nations crown, while victory over Wales last Saturday means they are still on course to claim a Grand Slam too. But they may have to do so without prop Joe Marler, who could be in big trouble after this weekend's action for a number of reasons. Six Nations chiefs have confirmed that they are investigating an incident in which it was claimed that Harlequins forward aimed a call of "gypsy boy" at Welsh prop Samson Lee - who is from an Irish traveller background.

The England forward apparently apologised to Lee after the incident, but if he is found guilty he faces a minimum ban of four weeks. But even if he escapes punishment for the incident, Marler will still likely serve a ban for this elbow to the face of Wales prop Rob Evans. https://twitter.com/TonduTurk/status/708960076900507648
