The PCB said in a statement that Nasir had been issued a notice under which he has been charged with multiple violations of the code of conduct in respect of spot-fixing and corruption issues.
The Board has already suspended Nasir for 12 months for not cooperating with the anti-corruption tribunal in the Pakistan Super League spot-fixing scandal which erupted last year.
The tribunal has already banned national team members Sharjeel Khan and Khalid Latif for five years on charges in the PSL spot-fixing scandal.
"PCB remains resilient in its fight against corruption in cricket. Upon action initiated by PCB the Anti-Corruption Tribunal has already banned Sharjeel Khan and Khalid Latif. The convictions of both cricketers were subsequently upheld on appeal by an independent adjudicator," the statement said.
Nasir, who once scored three ODI hundreds on the trot against India, has denied setting up meetings between Sharjeel and Khalid during the PSL with a suspected bookmaker, Yousuf Anwar, in Dubai.
