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

Hinkley 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."

Hinkley is confident Port Adelaide is free from the issues that have confronted the sport this year in light of the ASADA investigation into banned substance use.

Port Adelaide was an industry-leader when it became the first club to appoint an integrity officer following the release of an Australian Crime Commission Report into drugs in sport at the beginning of the season.

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

"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.

"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.
