Mark Jonkman's bowling action found to be illegal
The International Cricket Council today confirmed that an independent test had found the bowling action of Netherlands fast bowler Mark Jonkman to be illegal and, as such, the player has been suspended from bowling in international cricket.

A comprehensive analysis revealed that his action exceeded the 15-degree level of tolerance permitted under the relevant regulations.

The independent analysis was performed by Prof. Bruce Elliott, member of the ICC Panel of Human Movement Specialists, at the School of Sport Science, Exercise and Health, University of Western Australia (UWA), Perth on 30 July.

Prof Elliott, in his reported, concluded: "All deliveries recorded during Mr Jonkman's testing at the UWA exceeded the ICC tolerance threshold level of 15 degrees.

"Mean elbow extension levels of 32.9 degrees (±3.74) and 31.4 degrees (±4.52) for the length and yorker deliveries respectively, unfortunately show Mr Jonkman at more than double the allowable extension threshold.

"Additionally, a mean elbow extension level of 38.8 degrees (±3.73) for the bouncer delivery indicates that Mr Jonkman's extension levels increase significantly as he bowls the ball shorter."

Jonkman had been reported following the completion of a match between Netherlands and Ireland on 9 July at VRA in Amstelveen during the ICC World Cricket League Division 1. He was reported by on-field umpires Kumar Dharmasena of the Emirates International Panel of ICC Umpires and Buddhi Pradhan of the Associates and Affiliate Panel of ICC Umpires.

Jonkman can apply for re-assessment of his action after he has modified it in accordance with clause 2.4 of the regulations for the review of bowlers reported with suspected illegal bowling actions.

The 24-year-old from The Hague has the right to appeal against UWA's conclusions to the Bowling Review Group, in accordance with clause 2.3 of the regulations for the review of bowlers reported with suspected illegal bowling actions. Should he choose to appeal, he must lodge written notification with the ICC within 14 days of receiving the report.
