England head coach Trevor Bayliss hopes Jos Buttler will keep his emotions in check in the heat of the moment in future after being given an official reprimand for his angry exchange with several Bangladesh fielders on Sunday.
After being dismissed on review in the second one-day international in Dhaka, Buttler felt Bangladesh were too excessive in their celebrations, and a heated confrontation ensued before umpires intervened to send the England captain on his way.
While Buttler was merely given a warning for breaching level one of the ICC's code of conduct, his opposite number Mashrafe Mortaza and batsman Sabbir Rahman were fined 20 per cent of their match fees.
However, all three were given one demerit point, and should any of them reach four, they face being handed some form of suspension.
Bayliss has no problems with Buttler, skipper for the three-match series, standing up for himself, but has urged the 26-year-old not to cross the line.
Bayliss said: "He got a slap on the wrist and I am sure he will be doing his best to stay out of trouble in the future.
"I haven't read the match referee's report but the Bangladesh players were fined and Jos was warned for retaliating and that in itself tells a bit of a story.
"I have no qualms about the passion he shows.
"We are not going to back down from anything and we have some characters in the team who will not back down."
