The FA are reportedly investigating a celebration used by various Premier League players that references a website known for sharing pornographic videos on social media.
According to The Sun, Swansea City's Sam Clucas "mimicked the porn site's spying symbol" as he netted twice in his side's shock 3-1 defeat of Arsenal on Tuesday.
Southampton duo Charlie Austin and Jack Stephens also made the gesture when celebrating a goal back in December, while it has also been referenced by other sportsmen, namely boxer Kell Brook and snooker legend Jim White.
