The Pakistan Cricket Board has barred three players under international suspension from practicing at the National Cricket Academy.
PCB spokesman Nadeem Sarwar on Wednesday said Salman Butt, Mohammad Asif and Mohammad Amir have been informed that they cannot utilize practice facilities at the NCA.
Butt had been practicing at the NCA in Lahore since he returned from the tour of England last month.
The three players have been suspended by the International Cricket Council pending investigations into accusations of spot fixing first raised by a British tabloid.
All three have denied the allegations and have filed appeals against their suspensions. The ICC will hold a hearing at Doha, Qatar on Oct. 30-31.
