The tribunal said Ryder, who has been in self-imposed exile from international cricket since February 2012, tested positive after a domestic match in March this year.

It said Ryder's sample showed traces of the stimulants PBA and DEBEA and the batsman admitted he took two supplement tablets in the days before the test. The disciplinary body said it accepted Ryder's argument that he was not aware the over-the-counter product contained banned substances and he took it because he was struggling with his weight, not to enhance his on-field performance.
