Lisandro Martinez was sent off after 56 minutes against Leeds United

Manchester United defender Lisandro Martinez was sent off after 56 minutes for pulling the hair of Leeds United striker Dominic Calvert-Lewin at Old Trafford.

Martinez, 28, was shown a straight red card and will now face a three-match suspension.

United were trailing 2-0 after Noah Okafor's first-half double when the Argentine tried to stop the Leeds attacker by holding his hair in an off-the-ball incident.

Referee Paul Tierney was instructed to review the incident on the pitchside monitor by the video assistant referee (VAR) before sending off Martinez.
