Stephen Dank has been given five days to provide medical evidence about why he missed his own appeal against a lifetime ban or risk having his case finally thrown out.

Dank, who was found guilty of 10 breaches of the AFL's anti-doping code in April last year, was scheduled to appear before the AFL's Appeals Board on Monday for a three-day hearing.

But the board and counsel for both the AFL and ASADA received emails on Sunday informing them that Dank would not appear, seeking an adjournment and citing a family medical emergency which required his presence at hospital.

"We note it was Mr Dank's intention to appear in person, lead evidence and make oral submissions," the letter on behalf of Dank said.
