Gold Coast's win over Carlton has come at a cost with co-captain Steven May to miss around three weeks with a hamstring injury.
May chased Blues' star Patrick Cripps in the last quarter of the Suns' 26-point win at Etihad Stadium but pulled up suddenly clutching his left hamstring.
He immediately went to the bench where ice was applied and is set for a period on the sidelines.
"Steven May will miss at least two or three (games) ... at least three, I reckon, with that hammy," coach Rodney Eade said.
The news is a blow for Gold Coast, who were already missing centre half-back Rory Thompson (quad) against the Blues and face ladder-leaders Adelaide at Metricon Stadium in round five.

The Suns improved to a 2-2 record with the win but will also monitor David Swallow (ankle) and Michael Barlow (hamstring tightness) ahead of next week's big test against the Crows.
Co-captain Tom Lynch kicked a career-best bag of seven goals in the 17.6 (108) to 12.10 (82) win that was set up with a stunning seven-goals-to-one third quarter.
"If you were marking (Tom) out of 10 you'd probably give him a nine but he probably could have got a 10 if he'd held (a few more) marks," Eade said.
"But he was terrific. His leadership was fantastic.
"He's got a lot of improvement left in him. He's still young and he's still got parts of the game he's got to learn."
Two-time Brownlow medallist Gary Ablett found plenty of the ball again with 34 possessions, including 11 clearances, and a goal.
Jack Martin, Touk Miller, Braydon Fiorini and Aaron Hall were also important as the Suns cut through Carlton with blistering ball movement in the pivotal third term.
"I thought it was a great way to win ... I'm really pleased," Eade said.
"I thought the first half was a real wrestle and they were probably on top ... but I think we hung in there.
"Then after halftime I thought we broke the game open. It certainly wasn't pretty early but I was pleased with the way that we won."
Blues skipper Marc Murphy worked hard for his 28 disposals, but he didn't have enough support in a team who were on the wrong side of a 440-321 possession count.
Sam Docherty was poised in defence with 26 touches and 13 marks, while Levi Casboult and Jack Silvagni kicked three goals apiece.
