England wicketkeeper Jonny Bairstow is reportedly under investigation from the ECB following an alleged incident with Australian opener Cameron Bancroft.

Bairstow is alleged to have headbutted Bancroft at a Perth bar earlier this month while the England team was in Perth participating in their first practice match of the tour.

Police were not involved according to early reports, while it has also been reported that Bancroft, who lives in Perth, did not provoke Bairstow or retaliate in the incident.

The England and Wales Cricket Board released the following statement late on Sunday evening:

"At close of play in Brisbane today, we were made aware of allegations of an incident in Perth four weeks ago," the statement read.

"There has been no report of any incident from the venue, security or police and there was no injury reported.

"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."
