The ICC has suspended Netherlands fast bowler Mark Jonkman from bowling in international cricket after an independent test found that his deliveries exceeded the tolerance threshold level of 15 degrees for bending of the elbow.
The independent analysis was performed by Prof. Bruce Elliott, member of the ICC Panel of Human Movement Specialists, at the University of Western Australia (UWA) in Perth on July 30.
Prof Elliott, in his report, said, "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 by on-field umpires Kumar Dharmasena and Buddhi Pradhan following a match between Netherlands and Ireland on July 9 in Amstelveen during the ICC World Cricket League Division 1.
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. He also has the right to appeal against UWA's conclusions to the Bowling Review Group, within 14 days of receiving the report.
