Handballs, offsides and the impact of video assistant referees (VAR) have been huge points of contention in recent years, but is it now time to add hair pulling to the list? Sunderland defender Dan Ballard became the third player this season to be sent off for pulling an opponent's hair in Saturday's 1-1 draw at relegated Wolves. Referee Paul Tierney initially took no action, but showed a red card to the centre-back after VAR advised him to check the incident on the pitchside monitor.
