Salman Butt, Mohammad Asif and Mohammad Amir have been provisionally suspended by the International Cricket Council.
The game's governing body has charged the Pakistan trio with "various offences under Article 2 of the ICC Anti-Corruption Code for Players and Player Support Personnel relating to irregular behaviour during, and in relation to, the fourth Test between England and Pakistan at Lord's last month".
The under-fire trio have been at the eye of a spot-fixing storm since claims in the News of The World on Sunday and have withdrawn from the Twenty20 and one-day series against England, which is due to begin on Sunday.
But they would not now be eligible for those games anyway and will not be available to play any cricket until a decision is reached.
