PORT Adelaide ruckman Paddy Ryder has trained in headgear to protect his surgically-repaired cheekbone in a bid to take on Melbourne at the MCG on Saturday.

Ryder moved freely, but complained of having trouble seeing the ball when it was thrown high into the air.

He went through a series of drills with the Power's ruck coach Dean Brogan, picking the ball off the ground, marking at chest height and above his head and hitting targets by foot.

Power coach Ken Hinkley said Ryder got through all of the training session to put his hand up for round one selection.

"It's a precaution, it's more for Paddy to feel safe enough in and right now, he's playing," Hinkley said.

Ryder suffered a depressed cheekbone in the final quarter of the Power's JLT Community Series game against North Melbourne on March 9.

The 31-year-old will spend most of his time as a deep forward this season while also changing with former West Coast premiership ruckman Scott Lycett in the middle of the ground.

Meanwhile, Power star Robbie Gray ran on an AlterG Anti-Gravity Treadmill, but isn't considered in any doubt for his 200th game for the club.

Co-captain Ollie Wines completed full training in a pink cap to designate he's yet to resume full contact after having shoulder surgery.

Wines is scheduled to return between rounds three and four.

Defender Matthew Broadbent "nicked" his hamstring at training and won't play at any level this weekend, while key forward Charlie Dixon isn't expected back until at least between rounds four to six providing he doesn't have any more setbacks with his leg injury.
