Carlton are unsure whether veteran midfielder Bryce Gibbs will once again request a trade back to Adelaide at the end of the season after doing so last trade period.
Gibbs stunned the Blues late last year after wanting to head back to South Australia for personal reasons, although the Crows couldn't strike up a deal with Carlton, rejecting their demand of two first-round picks.
The 28-year-old is in career best form this season, and capped off an already impressive year with 43 disposals, 10 tackles, seven inside 50s and seven clearances in Carlton's 10-point win over Gold Coast on Saturday night.
Despite being contracted until the end of the 2019 season Gibbs' future at Carlton isn't set in stone, with Blues football boss Andrew McKay suggesting the club will deal with it at season's end.
"We think he's happy at Carlton, we'll just have to see what happens at the end of the year," McKay said.
McKay went on to say the Blues have not spoken to Gibbs about his off-season plans, although are hopeful he will see out the remainder of his two-year deal.
"We're just letting him play his footy.
"All we know is he's playing really good footy and all we know is he's contracted for another couple of years."
