Hugh Dallas has stepped down as the head of referees in Greek football.

The Hellenic Football Federation (EPO) made the announcement four days after matches were suspended indefinitely in the domestic league following an attack on an official.

Dallas, who was sacked from a similar role by the Scottish Football Association in 2010 after he sent a tasteless email about the Catholic church, was appointed head of the Greece's Central Refereeing Committee (KED) in the close season and was in charge of appointing referees for matches in the country's top two divisions.

He will remain as head of training for those officials.

His change in role comes after matches in Greece's professional leagues were suspended indefinitely after Christoforos Zografos, assistant director of the KED, was admitted to hospital following a violent attack.

"The KED have accepted the request of Mr. Hugh Dallas to no longer be responsible for the appointments of refereeing officials for Super League and Football League matches," said the EPO in a brief statement.

"Mr. Dallas will continue to be responsible for the education and training of referees in both professional categories. Both the KED and the EPO will hold an assembly to decide on to whom the responsibilities [of appointing referees] will be allocated."

Dallas was given the job after continued pleas from Greek clubs for a foreign official to take on the administrative role following several match-fixing scandals in recent seasons.
