The International Cricket Council confirmed on Monday that Mike Procter will step down as Emirates Elite Panel Match Referee to take over as Cricket South Africa's convenor of selectors.
Procter officiated in 47 Tests, 154 ODIs and 15 Twenty20 matches since becoming a match referee in 2002.
He will take up his new assignment on December 1 after overseeing the upcoming ODI series between Pakistan and the West Indies (in Abu Dhabi) and also Zimbabwe and Sri Lanka.
"On behalf of the ICC I would like to thank Mike for his service as an Emirates Elite Panel Match Referee," ICC Chief Executive Haroon Lorgat said in a statement.
"Speaking from personal experience I know that his new role as CSA's convenor of selectors, which he will assume on December 1, will be a challenging and rewarding one.
"However, I also know that Mike will bring to it all the cricket wisdom he has acquired over more than 40 years of top-level involvement," Lorgat said.
The Chief Executive also said the date of joining was formalised after negotiations between the ICC and the South African board and will help Procter complete his engagements.
"His start date with CSA, arrived at after negotiations between us at the ICC and CSA chief executive Gerald Majola ahead of CSA's announcement, allows Mike to complete his obligations as a match referee before assuming his new role.
"This is important because it sets a definitive mark between the end of one job and the start of another and, in terms of Mike's position as a match referee, it ensures the continued integrity and independence of that role.
"Mike carries with him the best wishes for the future of all those associated with the ICC," Lorgat added.
