Swansea City defender Ashley Williams and Leicester City winger Riyad Mahrez had to be separated after the Foxes 3-0 win against the Welsh side, according to reports.
The two wrestled in the first half, and it is believed they were both later involved in an altercation outside the home team dressing room before Mahrez was ushered out of the stadium.
It is understood that Williams then walked past reporters moments later asking where the Leicester bus was but according to the Press Association Sport, the Swans captain did not get his wish before heading back to the stadium.
When asked about the incident, Swansea manager Garry Monk said: "I would not know anything about it."
A Leicester spokesman denied that the Algerian international tried to get into the Swansea dressing room but declined to make any further comment.
The win saw Leicester go two points clear at the top of the Premier League while Swansea are just two points above the relegation zone.
