IT'S CLEAR the AFL has problems, says Port Adelaide coach Ken Hinkley, citing the ongoing investigation into Essendon's supplement program and Saint Ahmed Saad's failed drug test as proof.

Hinkley insisted the Power were clean but said he addressed players on Thursday to "remind" them how careful each of them must be in the modern game.

 

"I don't think the industry's on top of it at the moment," Hinkley said. 

"I think there's still some issues going on and the sooner all the information comes out I think everyone will be a bit better qualified to talk about it.

"We're very confident that we've got no issues." 

The Bombers' saga was further fuelled on Wednesday night with the airing of an interview with the club's former high performance manager Dean Robinson.

 

Robinson accused coach James Hird of driving the controversial supplements regime in 2011; Hird has since denied such claims.

 

Hours earlier the Saints revealed Saad had returned an irregular sample in July.

 

The unknown substance was legal for use outside of competition but illegal during competition.

 

"What happens now is all these things that keep coming up are great opportunities for us to remind our club and make sure that we're absolutely squeaky clean," Hinkley said. 

 

"Even as early as yesterday we've gone back to the boys and said 'you've seen what's happened, we've just got to be very, very careful'."

 

Hinkley's Adelaide counterpart Brenton Sanderson was asked the same question, but said Hinkley's answer was "perfect".

 

"I couldn't have said it better than what Ken said – perfect," Sanderson said.
