David Boon has been named match referee for the forthcoming Sri Lanka tour of Pakistan while Joel Wilson and Michael Gough will officiate the three ODIs in Karachi.
Former Australia cricketer Boon has been part of the ICC Elite Panel of Match Referees since 2001 and was one of the six match referees appointed for the World Cup in England and Wales.
Boon previously refereed in the three-match T20I series between Pakistan and the West Indies in Karachi in April 2018.
Gough and Wilson, both from the ICC Elite Panel of Umpires, will supervise proceedings in the three ODIs due to commence on September 27.
Gough has also visited Pakistan before when he fulfilled umpiring responsibilities in the Pakistan Super League earlier this year.
The upcoming tour of Pakistan is the Sri Lankan team's second trip to the country since they were attacked by militants in Lahore in March 2009.
They returned to Lahore in 2017 to play a solitary T20I, eventually losing the encounter by 36 runs under the leadership of Thisara Perera.
Elite Panel umpire Aleem Dar along with Ahsan Raza, Shozab Raza and Asif Yaqoob will also be in action in the six limited-overs fixtures.
The tour was initially hindered by information regarding a possible terror threat targeting the Sri Lankan side being received by its Prime Minister's office leading the government to conduct a reassessment of the security situation.
The series will now go ahead as planned following the permission granted by Sri Lanka's defence ministry.
