Argentina international Martinez missed the away win against Chelsea last weekend and will also sit out of the home games with Brentford on 27 April and Liverpool on 3 May.<\/p>\n
While hair pulling is not specifically mentioned in the Laws of the Game, it is categorised as ‘violent conduct’ because it cannot be considered as something you would legitimately do when challenging for the ball.<\/p>\n
United were trailing 2-0 in the second half when Martinez tried to stop Calvert-Lewin by holding his hair in an off-the-ball incident, after being caught in the face himself.<\/p>\n
Carrick argued Martinez’s sending-off was a clear and obvious error by Tierney, as he was “off balance and grappling”, adding the action was “not a pull, not a tug, not aggressive”.<\/p>\n
But after reviewing the footage, the panel wrote they could not say with confidence the contact by Martinez was small because Calvert-Lewin “had reacted in a manner that suggested that he had felt a certain amount of force exerted upon his hair\/scalp”.<\/p>\n
Calvert-Lewin confirmed after the game he did feel his hair get pulled so told the referee.<\/p>\n
“The commission members were unanimous that the referee could not be said to have made an ‘obvious error’ in dismissing LM [Lisandro Martinez],” the report says.<\/p>\n
It also pointed out cases need to be “truly exceptional” for a punishment to be deemed excessive, and did not agree that was the case here.<\/p>\n
Separately, the Premier League’s key match incidents (KMI) panel has reviewed the incident and voted 4:1 that the referee was right to issue a red card to Martinez.<\/p>\n
