United’s selection problems are compounded by a likely three-match ban for Lisandro Martinez following his dismissal against Leeds for a hair pull on Dominic Calvert-Lewin. While the club is appealing the decision, PGMO chief Howard Webb has previously clarified that hair pulling is now strictly classified as violent conduct.
Explaining the reasoning behind such red cards on the 'Mic'd Up' programme, Webb commented: "For some years now, actions where players have pulled an opponent’s hair is deemed as violent conduct. It is in the guidance we give to clubs before the season starts, the book that the Premier League produces, that grabbing someone’s hair with force is deemed as violent conduct and a player will be sent off."
