England's James Anderson has been fined 50% of his match fee after clashing with Runako Morton during the second one-day international at Edgbaston.
Anderson and Morton discuss their grievances on Wednesday
He appeared to impede the West Indies batsman as he ran between the wickets and words were then exchanged.
Anderson, who conceded 78 runs from his 10 overs, was found guilty of breaching clause 2.4 of the players' code of conduct by match referee Mike Procter.
It involves "inappropriate, deliberate physical contact" with another player".
A statement issued by the International Cricket Council confirmed Anderson had been found guilty of twice "nudging" Morton during his innings and then running towards him following his dismissal to start a "verbal confrontation".
"I have no problem with players being aggressive on the field because our game is all about passion and commitment. But, at the same time, they have to recognise they are role models watched by people all over the world," said Procter.
"Cricket is, after all, a non-contact sport and when players fail to recognise that fact and engage in needless nudges, then that is where we have to draw the line.
"James Anderson is not a player with a reputation for bad behaviour...and I am sure he will do everything he can to ensure there is no repeat of this unfortunate incident."
Morton was cleared of an offence under clause 2.8 of the code, which covers the use of offensive language or gestures.
"I concluded that Runako Morton was the victim of James Anderson's aggression, rather than guilty of bad behaviour," Procter added.
The ICC hope the fine will take the heat out of Saturday's final one-dayer at Trent Bridge.
But England skipper Paul Collingwood, interviewed immediately after Wednesday's match and before Anderson was fined, said he would not stop his players getting involved in "feisty" exchanges.
He said: "To be perfectly honest, I don't mind the boys getting stuck if they need to get stuck in. I don't mind that at all."
And opposite number Chris Gayle said: "We were just trying to get on top of them as early as possible and they did the same thing, so it was a little bit of give and take.
"I hope no-one takes it too seriously.

"To be honest we are aggressive people and in cricket we need to be more determined. Once you can get on top of opponents earlier the better you tend to play."
Another of England's pace bowlers, Stuart Broad, was reprimanded for wearing a white lycra bodysuit under his coloured one-day uniform.
That contravened regulations which ban any type of visible white clothing in matches played with white balls.
"Hopefully this sanction against Stuart will serve as a reminder to him not to wear such garments in the future," said Procter.
