PORT Adelaide coach Ken Hinkley is relieved All Australian ruckman Paddy Ryder is safe after foiling an alleged home invasion.

Ryder and his brother chased three would-be burglars from his house in western Adelaide, following them in his car in the early hours of Thursday morning.

Ryder caught one of the three men and brought him to back to his home where police were waiting.

Ryder trained with the Power at Adelaide Oval on Friday morning and will take his place in the side to face Fremantle in their round one clash on Saturday afternoon.

"We're really happy that Paddy and his family are safe and that nothing else has gone wrong in that space," Power coach Ken Hinkley told reporters.

"One thing I know is that Paddy is looking forward to playing round one tomorrow afternoon.

"The rest we'll leave alone, I reckon." 

Ryder is coming off the best season of his career when he was selected in the All Australian team for the first time and claimed the Power's club champion award.

His athletic style and ability to jump over his opposing ruckman is in contrast to the clever bodywork and manoeuvering of veteran Power big man Aaron Sandilands.

"It's a big challenge for Paddy and whoever goes up against him, Aaron's a big man," Hinkley said. 

"Watching him the last couple of weeks, he seems like he's up and about and he seems quite fit.

"It's a challenge for any team, but we're not unhappy with our ruck option."

Former Brisbane skipper Tom Rockliff will debut for the Power despite not playing any games in JLT Community Series because of a knee injury.

Rockliff is one of several midfielders who the Power can play in attack to help cover the loss of the suspended Robbie Gray.

"(Rockliff) has had a pretty good preparation albeit he hasn't played in the JLT games," Hinkley said.

"He's done a lot of summer training, so he's got a great base.

"That's not the issue.

"Every player out there tomorrow at the start will feel their lungs.

"He may feel it a little bit more because he hasn't had any games yet."

The Power thrashed the Dockers by 89 points when the teams met in the corresponding fixture in round two last year.

But Hinkley has been impressed with the pre-season form of the Dockers after they pushed Adelaide and easily accounted for West Coast.

"As we always know with Ross, they're a really well-coached side," Hinkley said.

"You can see their pressure is back up and about and they've got some quality players in the side.

"They're an exciting group and a Ross Lyon-coached group - you're in for a challenge."
