Stephen Dank was unrepresented at an AFL tribunal hearing which heard submissions for penalties against the controversial sports scientist on Tuesday.

The hearing, chaired by former Victorian County Court judge David Jones, reserved its decision on the sanctions, which will be released at a later date.

Dank, who was a central figure in the doping scandals at Essendon and NRL club Cronulla, faces a lifetime ban from professional sport in Australia for violations of the AFL’s anti-doping code.

The AFL confirmed Dank did not attend Tuesday’s hearing and he had no legal representative.

Last month, the AFL tribunal upheld 10 anti-doping infringements against Dank.

But he was cleared of 24 other alleged infringements.

Dank will have the right to contest the tribunal’s sanctions before an AFL appeals board.

The finding could delay the World Anti-Doping Agency’s proposed re-hearing of the case against 34 past and present Essendon players at the Court of Arbitration for Sport.

Earlier this year the players were cleared of taking banned peptide Thymosin Beta-4 by an AFL tribunal.
