Australia batsman David Warner has been stood down for the Champions Trophy encounter with New Zealand on Wednesday after allegedly being involved in a drunken altercation with England's Joe Root.
According to the Sydney Morning Herald, Root was in Birmingham nightclub with teammates Stuart Broad and Steven Finn in the early hours of Sunday morning following England's defeat of Australia the previous afternoon.
Warner was also at the venue and is reported to have become involved in a physical spat with Root, during which the Yorkshireman was caught with a 'glancing blow' on the chin by the 26-year-old Australian.
The England and Wales Cricket Board have confirmed Warner initiated an 'unprovoked' attack against a member of their squad, responding to an earlier statement from Cricket Australia.
It read: "Following a statement issued this morning by Cricket Australia, the England and Wales Cricket Board confirms that David Warner initiated an unprovoked physical attack on a member of the England team in a Birmingham bar following England's 48 run victory over Australia.
"Warner has admitted behaving inappropriately and has since apologised to the player involved who has accepted the apology.
"Following a full investigation the England team management has concluded that the England player was in no way responsible for nor retaliated to the attack.
"ECB has concluded that this is a matter for Cricket Australia and have no further comment to make."
Australia team management met with Warner on Wednesday in consultation with Cricket Australia officials in Melbourne to decide on an appropriate initial punishment - with the player dropped from the New Zealand match.
Warner will now face further disciplinary action after Australia have faced the Kiwis at Edgbaston, and the opener could be sent home from the tour of England as the Ashes series approaches.
