England in clear for Joe Root's bar bust-up with David Warner England batsman Joe Root's fight with David Warner won't lead to new rules being imposed on his teammates. ENGLAND'S cricketers will not face new ground rules as a result of David Warner's bar-room bust-up with Joe Root. Australia batsman Warner apologised for throwing a punch at his English counterpart in the early hours of Sunday morning, when members of both teams were out at The Walkabout Hotel in Birmingham. Warner has been banned by Cricket Australia until the first Test of the Ashes next month, but the England and Wales Cricket Board (ECB) are satisfied that none of the players present at the time, believed to include Root, Stuart Broad and Chris Woakes, did anything wrong. The ECB investigated the incident and concluded that no blame could be attached to Root or his teammates, and captain Alastair Cook has confirmed they had permission to be out following the 48-run win over Australia at Edgbaston. England assistant coach Richard Halsall said procedures would not be altered but did concede that the altercation would focus all players on their duties. ``I don't think it (ECB policy) will change because of what happened, but it is a reminder that there are standards expected of cricketers," he said. ``When playing for England you have responsibilities and that's been reinforced. ``It's about conducting themselves with maturity and if there's the same time frame (between games) the same decisions will be made because there was nothing wrong with what our players did. Halsall also suggested England were content with the punishment dished out to Warner, who was also fined $11,500 and is highly unlikely to start the Ashes without any match practice. ``The director of cricket (Andy Flower) was involved in our investigation, as was (one-day coach) Ashley Giles," he said. ``We've got procedures we go through for matters like this and we dealt with it internally. ``We were very satisfied with the accounts we were given and then it was down to Cricket Australia to deal with it as they wished. ``We would never attempt to tell another board how to go about their business and we were satisfied with what CA did.
