Neil Swarbrick, who is in charge of the Premier League's video assistant referee (VAR) system, will step down at the end of this season after a string of controversies.
In December, an independent panel made up of former players and representatives from the Professional Game Match Officials Limited (PGMOL) claimed that six VAR calls in the Premier League this season were incorrect. That number has since grown.
Lee Mason, the Premier League's first dedicated VAR official, left the organisation after making a mistake in the 1-1 draw between Arsenal and Brentford earlier this month. It appears Swarbrick will follow Mason out of the door in a few months' time.
