Australia batsman David Warner has been dropped for the country's Champions Trophy match against New Zealand on Wednesday, after allegedly being involved in a late-night tussle with an England player, Cricket Australia said.
The federation said in an emailed statement that the player had been reported for breaching the federation's code of conduct relating to "unbecoming behaviour".
Warner "was allegedly involved in a physical altercation with an England player in the early hours of Sunday morning following the ICC Champions Trophy match between the teams in Birmingham", CA said.
"Team management has stood down Warner pending the outcome of the hearing, meaning he will miss Australia's match against New Zealand in Birmingham tonight (Wednesday)," it added.
The England player allegedly involved in the incident was reportedly Joe Root, although this has not been officially confirmed.
CA said it would not comment further until after the disciplinary hearing.
Warner last month came under fire for a Twitter tirade directed at two respected Australian cricketing journalists after a story about corruption and fixing in the recent Indian T20 League was illustrated with a picture of him.
After posting a tweet with expletives aimed at journalist Robert Craddock, Warner took issue with Craddock's News Limited colleague Malcolm Conn in abusive tweets that sparked a back-and-forth exchange.
He was found guilty of breaching Cricket Australia's code of behaviour and fined Aus$5,750 (US$5,608).
