PGA Tour pro Grayson Murray reportedly shouted out during the meeting for Monahan to resign.
"We don't trust you Jay, you lied to our face," said Murray, as Monahan was addressing the room.
Rory McIlroy then reportedly shouted back: "Just play better, Grayson."
A source has since confirmed to Telegraph Sport that Murray responded "f*** off".
One PGA Tour pro competing this week revealed there is "no way players will be okay with this merger" following a leaked text.
Seven players have chosen to withdraw from the Canadian Open since the news emerged on Tuesday morning.
These players include Zac Blair, Charley Hoffman, Ben Griffin, Davis Thompson, Joseph Bramlett, Arjun Atwal and former US Open champion Webb Simpson.
It remains to be seen whether all these WDs were a result of injury or due to their initial feelings of the shock merger with LIV Golf.
Those seven PGA Tour pros have been replaced in the field by Sangmoon Bae, Kyle Stanley, Arjun Atwal, George McNeill, Kevin Stadler, Ted Potter Jr and Omar Uresti.
Recent PGA Tour winner Davis Riley withdrew from the tournament on Sunday night and he has been replaced in the field by Derek Ernst.
On Monday just before the shock LIV Golf merger, Byeong-hun An, Sam Stevens and Luke List were forced out of the tournament and were replaced by Derek Lamely, Tommy Gainey and Ben Crane.
McIlroy is the tournament favourite as he goes in search of a third consecutive title at the Canadian Open.
