The verbal gloves are off when it comes to the buildup to UFC 315, with the tension between the U.S. and Canada spilling into the card.
Even the style of trash talk came up for debate in the headline event between welterweight champion Belal Muhammad and challenger Jack Della Maddalena.
After Maddalena said it was time for Muhammad to retire, the champ countered that his Australian opponent isn't "really good at trash talk."
"I just can't wait for him to eat his words and eat these fists," Muhammad said.
Muhammad 24-3-0 with one no-contest will put his championship on the line for the first time and is one of two title fights. Kyrgyz-Peruvian champion Valentina Shevchenko defends her flyweight crown against Manon Fiorot of France in the co-main event.
