West Brom will take no further action over an incident in the dressing room following Saturday's 3-3 draw with Cardiff at the Hawthorns.
The events appeared in a newspaper on Tuesday, claiming West Brom players had traded blows after losing a stoppage-time goal to their fellow Premier League strugglers.
Albion released a statement playing down the bust-up, and refuting claims Saido Berahino suffered a head injury as team-mates traded blows.
A mistake from the England U21 striker, moments after West Brom had gone 3-2 ahead, led to Cardiff rescuing an unlikely point.
But while Albion confirmed there was a heated exchange among the players, the club insists the incident has been blown out of proportion.
"Tensions were understandably running high in the dressing room after Cardiff's late equaliser but the incident has been sensationalised in the media," a club spokesman said.
"What happened is not uncommon in a dressing room and shows that the players care. The players involved have apologised.
"The club has drawn a line under the matter and is now fully focussing on Saturday's important game at Norwich."
West Brom are lying in 17th place, three points better off than 18th-placed Cardiff, who have played one game more.
