GOLD Coast captain Tom Lynch will undergo knee surgery and miss the remainder of the season.

Lynch has suffered a recurrence of the posterior cruciate ligament injury that ruled him out of four games earlier this season and has been advised surgery is the best option.

The 25-year-old missed the final three matches of 2017 with the same problem.

Lynch is a restricted free agent being courted by a number of Melbourne clubs and could have conceivably played his last game in Suns colours.

"It’s really disappointing to know that I’m going to have to have surgery and not play out the season," Lynch said.

"I’ve been doing all I can to rehab the injury without requiring surgery. That has meant I haven’t been able to get out there and train with the team during the week like you normally would.

"We’ve been assessing my knee weekly and the latest advice recommends surgery and I’ll get that done as soon as possible."

Lynch said he was aware that now his season was over, speculation about his playing future would continue.

"Obviously there is going to be commentary around my contract with the news of me being ruled out for the rest of the season, I’m realistic to understand that," he said.

"Post-surgery I’m sure the time will come where I’ll sit down with my manager and work through what the best option going forward is.

"Clearly, I’ve got a decision to make on my future, but the reality is I haven’t made that decision."

Gold Coast general manager of football operations Jon Haines said surgery meant Lynch would not be available to play for four to six months.
