Trevor Bayliss has threatened to drop players from the England team after another late-night incident in Perth which saw Ben Duckett pour a drink over James Anderson, the Test vice-captain.

While Bayliss, the England coach, described the incident as "fairly trivial" in itself, it comes at a time when the team has been dogged by alcohol-related controversy and as they are trying to ensure all focus remains on retaining the Ashes. As a consequence, a furious Bayliss has described the incident as "just not acceptable" and admitted he "might review who is in the team".

ESPNcricinfo understands the incident occurred in the early hours of Friday morning - Bayliss had relaxed the curfew so players were allowed to remain out after midnight - in the same Avenue Bar in Perth in which Jonny Bairstow greeted Cameron Bancroft with a now notorious headbutt. There was no violence and no report of any trouble by the bar staff or to the police. Instead, it seems the ECB's security detail reported what happened to the team management.

While it might, in normal circumstances, have been ignored, the England team did not depart for Australia in anything approaching normal circumstances. Instead, they arrived amid increased scrutiny over their behaviour as a result of the Ben Stokes incident in Bristol. That interest reached fever pitch after Bairstow was alleged to have headbutted an opposition player.

With such distractions, the England team management thought they had made it crystal clear to the players how important it was not to be involved in any sort of issue or indiscretion. As a result, their tolerance is limited and Duckett is not likely to enjoy much benefit of the doubt.

Andy Flower, the England Lions coach, is leading the investigation into Duckett's behaviour and it is understood the ECB board and Andrew Strauss, the team director, have been informed. Duckett, who was due to play for the England XI in the two-day warm-up game in Perth over this weekend, was dropped from the side. While the early signs are that Duckett might escape being sent home from the tour - the ECB is keen to avoid the headlines that may generate - it does seem safe to conclude he has done his chances of future England recognition great damage.

Bayliss made his views completely clear after having to get involved once again. "It's a fairly trivial incident but, in the current climate, it's just not acceptable," he said. "Everyone has been warned how small things can be blown out of all proportion. And the ECB have been quite strict to the boys in terms of their message. It's quite simply unacceptable.

"I am fed up. Very much so. I'm here to coach the team and I end up spending most of my time in front of cameras trying to explain some behaviour the boys have been warned about.

"I'm not sure exactly what more I can say to them. I'm sure there will be some stern words from above. I might review who is in the team. You can't keep making the same mistakes. Look, most of the guys are fine. But somewhere along the line, some guys have to pull their heads in. It's totally unacceptable."
