Gary Ablett's much-anticipated return from a shoulder injury has been put off for at least another week, with the Gold Coast superstar not named for Sunday's clash with Carlton.
Ablett has been sorely missed by the Suns since he succumbed to a nagging shoulder complaint after round two this season, but as recently as Wednesday coach Rodney Eade had expressed confidence the 31-year-old would return against the Blues.
However, the dual Brownlow medallist didn't appear in an extended squad on Thursday night.
"We were hopeful that Gary would be available for selection, however it was determined that Gary wasn't ready to return this weekend," Suns football manager Marcus Ashcroft told the club's website.
David Swallow (knee) and Rory Thompson (hip) had also been in the mix to return from injury, but won't make the trip south for Sunday's clash at Etihad Stadium.
The news wasn't all bad for the Suns, who regained important defender Steven May (groin) and talented midfielder Harley Bennell (calf) from injury, with Sam Day, Alex Sexton and Matt Shaw also named in the 25-man squad.
Carlton were bolstered by the return of full-back Michael Jamison from a calf injury, but lost Bryce Gibbs to a two-match suspension and Andrew Walker to a knee injury.
David Ellard, Jason Tutt, Blaine Boekhorst and Nick Holman were also included in the squad that will be trimmed by three players on Friday.
