Australia batsman Cameron Bancroft is said to have clashed with Jonny BairstowHas Jonny Bairstow had discipline trouble before?
There are no police reports, but it is believed that European Central Bank conducted an internal investgation on the matter. "Following an initial conversation with Jonny Bairstow tonight we understand the context and will follow up with England players and management after the Brisbane Test", ECB spokesman said in a statement.
The incident reportedly occurred at the Avenue Bar in Perth ahead of England's warm-up game against Western Australia.
However, the news immediately brought back memories of Warner's infamous altercation with now England captain Joe Root in the Birmingham Walkabout bar during the 2013 Champions Trophy tournament.
England go into the final day of the first Ashes 2017-18 Test with just 56 runs to defend on the final day with Australia having all their 10 wickets intact.
Bancroft wasn't yet named in the Australian squad for the five-match Ashes series at the time of the incident. When he handed it to him their heads touched and they carried on drinking together. Very odd I know but nothing malicious at all.
"Cricket Australia did not want to become involved last night but England suspect the Australians have allowed their media to fire bullets for them". The suggestion of a headbutt is complete b*******'.
Bairstow, meanwhile, was one of three players who were fined by the European Central Bank last month and accepted formal written warnings for "unprofessional conduct - unrelated to the investigations into Ben Stokes and Alex Hales".
At the start of the tour, head coach Trevor Bayliss confirmed that England's players would not be subject to curfews, although the expectation would be that they were to abstain from drinking between matches.
There is no doubt that this incident would never have been seen as being anything wrong had Stokes not rewritten the rules by becoming embroiled in a violent incident at the Mbargo bar after a one-day global in Bristol. Bairstow is believed to have apologised at the time.
England were clearly inclined to give Bairstow, who has received enormous praise and respect after the release of his book A Clear Blue Sky, the benefit of the doubt and sensed Australian mischief at work.
