There seems to have been a recent change in stance by the ICC in clamping down on bowlers with suspect actions. New Zealand's Kane Williamson (July 2014), Sri Lanka's Sachithra Senanayake (July 2014), West Indies' Shane Shillingford (December 2013), and South Africa's Johan Botha (October 2013) have all been reported and subsequently banned from bowling. Bangladesh's Sohag Gazi ((August 2014) and Zimbabwe's Prosper Utseya (August 2014) have been reported and will undergo testing.
And now the brakes have been put on Ajmal's career as well.
Interestingly, all the above bowlers have been off-spinners, and conspicuously, all have been reported in games with English umpire Ian Gould officiating.
