White, who played in Carlton's win against St Kilda at Etihad Stadium the night before, is co-operating with police. The Blues have the bye this week.

"We are aware of an altercation on Tuesday night," the club said in a statement.

"The club and Simon have been co-operating with police. As the matter is being investigated we are not in a position to go into any more detail."
