GOLD COAST co-captains Steven May and Tom Lynch are both out of Saturday's match against the Western Bulldogs, with Lynch to miss a month with a knee injury.

Following surgery to a broken finger last week, May has suffered an infection and will miss one match, while Lynch has succumbed to a recurrence of the PCL injury that sidelined him late last season.

Lynch missed the final three rounds of 2017 and has been carrying the problem for a couple of weeks.

He will miss matches against the Bulldogs, Melbourne and Port Adelaide before returning against Geelong in round 11 at Metricon Stadium following the Suns' bye.

MATCH PREVIEW: Western Bulldogs v Gold Coast

Despite the reoccurrence of Lynch's injury, Gold Coast's general manager of football operations Jon Haines says there are no long-term concerns.

"We certainly want to look after Tom’s long-term health and set him up for the back half of the year.

"It was a really collaborative decision that we had yesterday, and Tom was heavily involved in the process as well." 

Lynch is a free agent at the end of the season and has started his campaign in patchy form, kicking 14 goals from six matches, including eight in round two against Carlton.

Meanwhile May, who suffered the fractured finger against the Brisbane Lions in round five, will also miss this weekend.

"Off the back of the surgery there’s been a small infection in that particular area, so he’ll miss this week and we’ll assess him next week."
