RYAN Burton looks set to return for Port Adelaide's crucial match against GWS on Sunday.

THE FULL INJURY LIST Who is racing the clock?

The defender has been held out with a knee injury but was close to playing last weekend.

"He's (Burton) still got a few more boxes to tick, but we'd like to think he'd be up for selection," Port Adelaide assistant coach Jarrad Schofield said on Tuesday.

Exciting utility Xavier Duursma is in the mix to return from a hamstring injury too, but his prospects are less likely than Burton's.

"Not too sure on that one, he's (Duursma) another one that we've got to get through training," Schofield said.

"He'll be thereabouts, but he's still got a few more boxes to tick."

Schofield says there's no need to make wholesale changes to the midfield group, but conceded that area needed attention after Brisbane's on-ballers ran riot.

"We weren't great at the centre-square bounce," he said.

"Probably our contest work was below the level we've been so good in."

That area will be cause of extreme concern this week as Giants midfielders Callan Ward and Tim Taranto have got the all clear for selection.

External pressure has mounted on forward Connor Rozee, but Schofield was quick to pump the brakes despite the young gun gathering just 36 disposals across his last three games.

"We'd all like to touch the footy more," Schofield said.

"He hasn't been at the lofty heights that we expect of Connor, but he's in his second year and let's not put too much expectation on the young man."
