Adelaide are tightlipped at speculation Carlton star Bryce Gibbs wants to be traded to the South Australian club.
Adelaide won't comment on rumours that SA-born Gibbs is holding talks with the Crows.
"We don't have any comment to make on trade rumours or innuendo," a Crows spokesman said on Thursday.
Gibbs has three years to run on his lucrative contract at Carlton believed to be worth about $600,000 a season.
The 27-year-old is understood to have rejected advances from Adelaide and Port Adelaide in 2013 before re-signing with the Blues.
Gibbs, a veteran of 209 AFL games who won Carlton's club champion award in 2014, is the latest high-profile midfielder with rumoured links to the Crows.
Brisbane Lions captain Tom Rockliff and Port Adelaide's Hamish Hartlett are others while the Crows have denied rumours they offered a deal to Richmond ace Dustin Martin.
