Pakistan One-day captain Shahid Afridi and head coach Waqar Younis have been summoned as witnesses by the International Cricket Council (ICC) anti-corruption tribunal, which will consider spot-fixing allegations against three Pakistan players.
Suspended Test captain Salman Butt and pace bowlers Mohammad Asif and Mohammad Amir are due to appear before the three-member tribunal in Doha from January 6-11.
The trio were suspended by the ICC in September while touring England with the national team after a report in the News of the World newspaper alleging they had taken bribes to arrange for no-balls to be delivered in the fourth Test.
The Pakistan Cricket Board said in a statement that the ICC had asked for Waqar and Afridi to attend the hearing. It said the pair would attend either in person or through a teleconference.
Afridi is returning home after a Twenty20 series in New Zealand but Waqar will be helping the team prepare for the first Test.
