PORT Adelaide forward Robbie Gray has failed to complete his side’s training session at Jiangwan Stadium in Shanghai.

The Power trained for around 90 minutes in 30 degree heat on Thursday afternoon, with most of the session based around match simulation.

While Gray took part in the earlier parts of training, he finished the hit-out on the bench with his right calf strapped and iced.

Power ruckman Paddy Ryder told AFL.com.au after the training session that he was still confident Gray would be fit to face Gold Coast in Sunday's historic match.

"Yeah, he'll be good. He always gets up," Ryder said. 

"He's vital to us. He got out there and had a few kicks and a few runs but I think the physios are just looking after him a bit, which I'm more than happy with."

There has been ongoing speculation Gray is carrying an injury since he was held goalless against West Coast last Saturday.

Earlier on Thursday, coach Ken Hinkley brushed aside suggestions that Gray's poor showing in the loss to the Eagles was due to injury.

"He's fine; he's here; he's in Shanghai; he's ready to play," Hinkley said at a promotional function for the match.

"Robbie is no different to any other player. He has niggles that he deals with and he'll be fine to play."

Hinkley was asked about the ongoing speculation over Gray's fitness.

"Robbie was beaten by his opponent on the weekend," the Power coach said.

"I've had that conversation with Rob - he gets embarrassed by some of the hysteria that goes around about his groins or not his groins.

"Rob is just a normal player and he can have bad games ... hopefully, not again on Sunday."

The 90-minute training session was Port Adelaide's first at Jiangwan Stadium since arriving on Wednesday afternoon.

Gold Coast will hold its first hit-out at the venue on Friday afternoon.
