North Queensland coach Paul Green and captain Michael Morgan were reportedly involved in a heated incident at the Cowboys' post-match function after their big loss to Newcastle last weekend.
Just hours after their 36-point loss to the Knights, Green and Morgan were having some drinks with some club corporates, before the pair began arguing with each other.
The Saturday Telegraph understands Morgan took offence to some words from Green, asking his coach whether he had doubts about his leadership.
The pair have reportedly spoken about and made up after the incident, although it's just another incident in a poor season for North Queensland.
The Cowboys defeated the Panthers on Friday night, which temporarily lifted them above the Dragons into 14th place, as they sit with eight wins and 14 losses.
