RICHMOND vice-captain Brett Deledio says he's "at ease" with the Tigers' protocols when it comes to ensuring players avoid taking banned substances.

With Collingwood's Lachlan Keeffe and Josh Thomas under provisional suspension after testing positive to a banned substance, Deledio was quizzed on Tuesday about Richmond's practices.

He said players were required to record online everything they took.

"If it is from the steak I think they've been a little bit unlucky, but the good thing for us is we can check and make sure it's all clear and you don't have to worry," Deledio said.

"Any questions we've got, we just go straight to the doc or our nutritionist.

"If you've got any doubts, ask the question and therefore you should eliminate most risk."

Deledio said the players knew they should ask the club's medical staff about anything that could be dubious.

"You've got to tick off everything these days, and we fill out a form online every week to make sure we notify the AFL and the doctors of what we're taking," he said.

"We do clarify and make sure we check and double-check.

"It is onerous at times, but that's what you've got to do as a professional athlete."

Deledio also said he was satisfied with the AFL's three-strike illicit drugs regime.

"It's a policy that's been put in place by the AFL and ASADA and it's something we all have to live by," he said.

"I haven't got a problem with it."
