PCB chairman Zaka Ashraf, though, said he is not in the know-how about Rauf's removal from the elite panel of umpires from next month's Champions Trophy to be held in England.
"It (Rauf's withdrawal) is not in our knowledge. He did not go to India (to officiate in IPL) with our permission. We are not involved in the umpires business in IPL.
"As per the rules, the Pakistani umpires will have to sign a contract with the Board," he added.
The spot-fixing saga in the ongoing IPL took a dramatic turn today with ICC withdrawing controversial Pakistani umpire Rauf from the panel of match officials for the Champions Trophy as his role in the scandal is being investigated by the Mumbai Police.

The PCB chief, however, said that the spot-fixing scandal in IPL, which is getting murkier day by day, is a wake up call for the BCCI.
"I don't know why things are not tightened or managed in a proper way in IPL. All the mud-slinging is coming up in the IPL. It's a wake up call for the organisers of IPL," Ashraf told 'Times Now'.
Rauf was also embroiled in a controversy last year when a small-time model named Leena Kapoor accused the Pakistani umpire of sexually exploiting her for months before refusing to marry her.
