Asif was alleged to have sent down no-balls at pre-arranged times
Pakistan seam bowler Mohammad Asif has withdrawn his appeal against a provisional suspension imposed on him by the International Cricket Council.
Asif, fellow paceman Mohammad Amir and batsman Salman Butt were suspended following spot-fixing allegations made during Pakistan's tour of England.
The 27-year-old said his legal team had not had to prepare his case, but he would challenge the ban in due course.
Appeals by Amir, 18, and Butt, 26, will be heard in Dubai next weekend.
The trio will not be involved in Pakistan's upcoming series against South Africa in Dubai and Abu Dhabi.
However, Asif could not have played in that series in any event as he is banned from entering the United Arab Emirates after being detained for possession of opium at Dubai airport in 2008.
On Friday, the ICC issued a brief statement confirming Asif had withdrawn his appeal against the provisional ban.
However, a few hours later he insisted he was innocent of any wrongdoing and added: "I decided to withdraw the appeal against the suspension for now since we got the detailed documents relating to the case late from the ICC and my lawyers need more time to prepare for a detailed challenge."
The three players were questioned by British police following allegations published in the News of the World about the final Test against England at Lord's.
It was claimed Asif and Amir deliberately bowled no-balls at pre-arranged times during the Test, with skipper Butt also said to be involved, in return for money from a bookmaker's "middle man".
Fellow seamer Wahab Riaz was also questioned by police, whose investigation - separate from the ICC Anti-Corruption and Security Unit's (ACSU) own investigation - remains ongoing, although no criminal charges have yet been brought.
On Saturday, meanwhile, the ICC's Pakistan Task Team (PTT) met for the first time by teleconference.
The PTT, which was set up in 2009 to help Pakistan restore its cricketing reputation, reminded the Pakistan Cricket Board to encourage all its players to disclose any relevant information they might have to the ACSU.
ICC chief executive Haroon Lorgat said: "Every single player who cares about the game should step forward and help us to eradicate corruption from the game - such disclosures will be treated in strict confidence."
PTT chairman Mr Clarke added: "The task team urged everyone to support the PCB to reform its cricket and governance models and the important role PBC chairman Ijaz Butt has to play in this regard.
"An independent board would help it to regain its glory and ensure long-term success."
The ICC also wants every player to sign an anti-corruption declaration before they play their next match.
