Fremantle contested beast Nat Fyfe has declared himself a certain starter for round one despite missing Freo's two JLT Community Series games with an elbow injury. 

Fyfe underwent minor surgery on his right elbow shortly after appearing in the AFLX tournament. 

The 27-year-old said he tested his elbow in contact exercises at training on Sunday and he rated himself a certainty to face North Melbourne in the season opener.

"I’m happy to announce that I couldn’t be more ready for round one," Fyfe said at the season launch.

"I did 10km of work on Sunday with contact and marking so I’m ready to go."

Fyfe said he believes the new centre bounce starting positions will play to his strengths.

The superstar onballer's absence was keenly felt on Sunday when the Eagles dominated stoppages (55-27) and centre clearances (18-5) in Freo's 51-point loss in Mandurah.

"I think it shows the immaturity of our team somewhat," Fyfe said at Fremantle's season launch.

"A great first half, we moved the ball well, we were competitive around stoppages, but in that second half a quality team was able to get hold of us – particularly out of the middle.

"We're seeing some changes with the new 6-6-6 structure at centre square bounce, that's having an effect on teams and our team really needs to evolve quickly to be able to handle that, so some immaturity.

"Against Collingwood, we won the clearances (41-38), we were really competitive, and against West Coast the opposite happened, against two quality midfields.

"It just shows we're going to have some ups and downs as the season goes.

"We get David Mundy back in the midfield (this season), I'll be coming back in, that means there's not as much load on (Andrew) Brayshaw, (Adam) Cerra and younger players going through that midfield.

"I don't think it's panic stations, but it just shows we've got kinks to iron out."
