He underwent assessment at England's Loughborough University on Nov.1.
"Saddened to know the result of my bowling action from ICC, it would never pull me down, will never give up, worked so hard to remodelled it and will work again twice harder to get better to serve my beloved country Pakistan", said Hafeez via twitter.
Pakistan all-rounder Mohammad Hafeez will not be allowed to bowl in global matches after the worldwide Cricket Council (ICC) found his action to be illegal.
This is not the first time the veteran Pakistani all-rounder has been banned from bowling in worldwide cricket. They have risen to the top of the T20 rankings and won the Champions Trophy in June in some part because Hafeez was back bowling - his availability offered Pakistan not only control at one end, but the flexibility to choose a number of attack-minded, wicket-taking options. In April 2015, his bowling action was passed as legal by the governing body.
Under clause 4.5 of the regulations, Hafeez can apply for a re-assessment after modifying his action. "Work harder on his batting", said the former fast bowler.
Mohammad Hafeez has announced that he will not feature in this year's Bangladesh Premier League (BPL) and continue to work on his bowling action. However, a few months later, his action was reported during the Galle Test versus Sri Lanka.
