Manchester United defender Marcos Rojo will face no disciplinary action over his alleged stamp on Eden Hazard near the end of Monday's FA Cup quarter-final at Stamford Bridge.
The Argentinian defender appeared to plant his studs in the chest of Hazard after the Belgian went down near the touchline, but referee Michael Oliver said in his report that he had witnessed the incident and did not regard it as violent conduct and worthy of a red card.
While that will surprise many in the light of Tyrone Mings's five-match ban for a stamp on Zlatan Ibrahimovic in United's home game against Bournemouth this month, the FA is powerless to act if the referee says he witnessed the event. It is only when he says he did not see it that the footage is examined by a panel of three former referees who decide what action they would have take.
United have been charged by the FA with failing to control their players after Ander Herrera's red card. The club, who face a hefty fine, have until 6pm on Friday to reply.
