Malcolm Waller, the Zimbabwe part-time offspinner, has become the latest bowler to be pulled up by the ICC for a suspect bowling action. Waller will now have to undergo testing within 21 days, and can continue to bowl in international cricket until the results of the tests are announced.

Waller was reported during the second Test against Bangladesh, during which he took six wickets. "The match officials' report, which was handed over to the Zimbabwe team manager Mufaro Chiturumani after the Test concluded on Friday, cited concerns about the legality of the 30-year-old's bowling action," an ICC release said.

The ICC has been increasingly vigilant about dodgy bowling actions this year, with bans being handed to high-profile players like Pakistan's Saeed Ajmal. Waller's team-mate, Prosper Utseya, was also reported three months ago and was suspended from bowling in October.

The ICC crackdown has hit offspinners the hardest: besides Ajmal and Utseya, Sri Lanka's Sachithra Senanayake, Bangladesh's Sohag Gazi, West Indies' Shane Shillingford and New Zealand's Kane Williamson have also faced scrutiny over their action.
