An unnamed PCB spokesman was quoted as saying by the 'Dawn' newspaper that media reports that claimed that Malik's action was reported for being suspect, were baseless.
"We have not received any report on Shoaib Malik's bowling action from any umpire or referee during the Quaid Trophy," a PCB spokesman told the newspaper.
Malik also rubbished the reports and said he was working hard to make a comeback to the national side for the upcoming World Cup in Australia and New Zealand.
"I am regularly playing four-day games and will not hesitate in playing club or league matches for rediscovering my form," Malik, who married India's tennis star Sania Mirza, added.
Malik expressed a desire to play in New Zealand in Pakistan's next assignment, saying he would not disappoint the selectors if given a chance.
