SUPERSTAR free agent Patrick Dangerfield intends to walk out on Adelaide after eight seasons and is expected to join Geelong in October.
The club confirmed on Wednesday that the 25-year-old would exercise his right as a restricted free agent and "return home to Victoria".
Dangerfield is widely tipped to sign with the Cats given the club's proximity to his hometown Moggs Creek. AFL.com.au believes a five or six-year deal is on the table worth $800,000 a year.
Adelaide now has the chance to match any offer the Cats make and CEO Andrew Fagan said the club would consider its options.
"Whilst disappointing, we understand that Patrick's decision has been made for personal reasons," Fagan said.
"We will now consider our options, however, our members and supporters should rest assured that in doing so we will make decisions and take action that is in the best interests of our football club.”
Dangerfield's performance in 2015, amid intense and constant questioning over his future has been nothing short of phenomenal.
He averaged a career-best 26.8 disposals a game and was ranked second in the League for contested possessions.
He is expected to take out the Malcolm Blight Medal as club champion on Saturday night and is one of the favourites for Monday night's Brownlow Medal.
Dangerfield was drafted by the Crows with pick No.10 at the 2007 NAB AFL draft, taken ahead of home-town favourite Brad Ebert.
He has finished inside the top three in Adelaide's best and fairest in each of the past three seasons; he was runner-up to Scott Thompson in 2012 and third in 2013 and 2014.
