TOM LYNCH has declared his fitness for Saturday's match against Geelong but is still up in the air about his long-term future – despite a cheeky quip about Melbourne weather.

The Gold Coast co-captain missed three matches with a knee injury but went through an extensive session on Monday to prove his availability to play the Cats.

"I'm fit to go, 100 per cent I'll be right," Lynch said on Tuesday morning.

Lynch carried the injury for a week or two before deciding to take a break to get it right.

He said although it was frustrating watching the Suns lose three games while he watched from the sidelines, it was the right decision.

"It got to a point where I needed a rest," he said.

"I couldn't keep going or it would hinder me in the back half of the year.

"Three weeks off, plus the bye freshened me up.

"I managed to get some good training into the knee and I feel a lot more confident. The knee is in a much better spot than it was."

Although his immediate future is locked in, the restricted free agent said a week in Melbourne over the bye was not enough to clear up his thoughts beyond 2017.

"I was pretty focused on my knee, that's all I could think about," he said.

"I just narrowed my focus on that and now I'm looking forward to getting back out there.

"I was pretty happy getting back to the warm weather; it was a bit cold down there."
