Crows star Nathan Bock has been charged by police with assault and causing damage after an incident at the General Havelock Hotel in the early hours of Sunday morning.
Bock was detained by police and then released with a date to appear in court later in the year, although he might face further action from the AFL for bringing the game into disrepute.
Adelaide general manager John Reid released a statement on Sunday confirming the incident.
"The club is gathering more information regarding the incident and once we have all the details the club will advise all concerned on what action it will take from a club and AFL perspective," the statement read.
"We will endeavour to do that as soon as possible. In the meantime there will be no other comment on the matter."
Bock enjoyed a standout season in 2008, earning All-Australian selection at centre half-back, and has only missed one match since the start of the 2007 season.
