The Telegraph have released footage of the confrontation between Sale Sharks headcoach Steve Diamond and Independent journalist Sam Peters.
Peters took to social media to “confirm an altercation took place”.
A spokesperson said the RFU would “look into it” if a complaint is received.
Any charge against Diamond would be brought under the banner of bringing the game into disrepute.
Despite a short video of the pair arguing appearing in the Sunday Telegraph, and a number of reports giving detail of the altercation, the game’s national governing body has not had a formal complaint.
