Cricket Australia (CA) is investigating an alleged physical altercation involving allrounder Andrew Symonds.
Symonds was reportedly drinking at the Normanby Hotel in Brisbane on Sunday evening when the alleged fight started.
“We are getting as much information as possible to establish what did and did not happen,” said a CA spokesman.
“We understand there was an altercation.”
The incident reportedly happened on Sunday night after Australia had completed a 149-run victory over New Zealand in the first Test at the Gabba.
Police were not called and Symonds was not asked to leave the hotel.
Symonds recently admitted having drinking problems, and had been kicked out of the Australian one-day team for the 2008 series against Bangladesh because he skipped a meeting to go fishing.
He returned to the Australian team for the first Test against New Zealand.
Symonds was also suspended in 2005 for turning up drunk to a match against Bangladesh in Wales.
