KEN Hinkley has confirmed Hamish Hartlett, Chad Wingard and Jackson Trengove will all play on Sunday against Fremantle in Perth.

Hinkley said the trio, who were hampered by groin, knee and shoulder injuries respectively, had since done "a lot of training".

"They (Wingard and Hartlett) will both play this week and Jackson Trengove's the same," Hinkley said on AFL.com.au’s First Bounce.

"They haven't played footy though [this pre-season] and that's the concern we have with all those players.

"But they're fit, they're ready to play and I'm not in the habit of not picking good players."

It’s a major boost for the Power on the back of Tuesday’s news that Paddy Ryder and Angus Monfries would be available to play in Round 1 after being found not guilty at the AFL anti-doping tribunal.

Hinkley admitted he had some concern about the match fitness of the former Essendon pair, after provisional suspensions held them out of the NAB Challenge.

That robbed them of match practice, but Hinkley said otherwise full pre-seasons meant they were fit and available for Sunday.

"There's some concern about match practice, but there's concern about other players. That's just the way it is," Hinkley said.

"I could sit here and say no, but reality says that there would be a little bit of concern about that.

"They haven't missed any training, they're as fit and as ready to go as anyone on our list … that's the key for us."

Port Adelaide faces Fremantle at Domain Stadium on Sunday at 4.40pm WST (6.10pm CST).
