The Pakistan Cricket Board has backed the decision of an anti-corruption tribunal which banned three players for spot-fixing during a Test match.
Batsman Salman Butt and seam bowlers Mohammad Asif and Mohammad Amir were banned for a minimum of five years.
All three players were found guilty by the International Cricket Council tribunal after a six-day hearing in the Qatari city of Doha.
Former captain Butt, 26, was handed a 10-year ban, half of which was suspended, Asif, 28, was banned for seven years, two suspended, and 18-year-old Amir was given a five-year ban.
