The Gold Coast Suns enjoyed a 26-point win over Carlton last night, to sit 2-2 after the opening four rounds.

Tom Lynch kicked seven goals in the win, but it is not all good news for the Suns, who could be without three of its stars next week.

Co-captain Steven May suffered a hamstring injury during the win and is expected to miss at least three weeks.

Meanwhile,  Michael Barlow and David Swallow will face fitness tests during the week, after suffering hamstring and ankle injuries respectively.

"Steven May will miss at least three, I reckon," coach Rodney Eade said post-match.

"Michael (Barlow) got tight early in the first quarter, so it was more precaution.

"David Swallow tweaked his ankle – that's why he was playing forward most of the night. It was a pretty gutsy effort for David but he should be ok next week."

In better news, the Suns will most likely regain Rory Thompson and Pearce Hanley for the side's clash with Adelaide at Metricon Stadium next Saturday afternoon.

After a tight first half, Gold Coast defeated Carlton 17.6 (108) to 12.10 (82).

Lynch booted seven goals in a dominant display, while former skipper Gary Ablett collected 34 disposals, five marks, four tackles and kicked a goal.
