The Swans, who are not yet assured of Premier League survival, declined to reveal the names of the players involved but says the club has now moved on from the situation.
"Yes, there were a couple of incidents between certain players, which the club does not condone yet understands," confirmed a Swansea spokesman.
"They were quickly dealt with and everyone moved on."
As recently as January, the Welsh side had a separate bust-up when defenders Chico Flores and Garry Monk caused police to be called to the training ground by a member of the public.
Monk would then take over from the sacked Michael Laudrup as caretaker manager but the side – who put forth a respectable effort in European competition until they were eliminated by Napoli – have since been pulled into the scrap for survival.
Swansea have only won two of the 13 matches Monk has overseen as head coach since taking over from Laudrup in February.
"These things often happen on training grounds up and down the country, so despite the media reports, Swans fans shouldn't be concerned," added the spokesman.
"The squad had just returned to training on the back of a disappointing defeat at Hull and their frustration at not getting the result they wanted boiled over during a full 11 v 11 practice match between the group.
"There are a lot of winners within the squad and they want to finish the job. You only have to look at the commitment and effort they put in against Chelsea on Sunday with just 10 men to see that.
"It certainly looked like a team that was fighting for each other rather than against each other - as is being suggested in some quarters."
