Floyd Mayweather and Conor McGregor met Friday for one final time before their Saturday night fight for an official weigh-in.

While boxing weigh-ins are normally relatively uneventful, these two fighters’ penchant for trash-talking led to some sparks in their last public event before the bell rings.

The fight is set for 154 pounds, and both men hit the number with relative ease. Mayweather, having fought as low as 145, came in at a comfortable 149.5 pounds, while McGregor, who has made a variety of weights to meet different opponents in the octagon, stepped on the scale at 153 pounds.

While fights at 154 pounds are normally required to be fought with 10-ounce gloves, a one-time waiver was granted by the Nevada Athletic Commission to allow the bout to go on with eight-ounce gloves after both fighters campaigned for the change.

After the fighters were done, they met in the center of the stage for one last photo op. Mayweather remained stoic, while McGregor started screaming like a man mad with self-confidence. You can watch their exchange below.

In an interview after the weigh-in, McGregor repeated a prediction, telling FS1, “Knockout. Fourth round.”

Meanwhile, Mayweather had a quiet confidence of his own. When a reporter attempted to ask if the gravity of this being his last planned fight had washed over him yet, he ignored the question, replying by saying, “This will be Conor McGregor’s last fight also.”

The main card starts tomorrow at 9 p.m. ET, with the headlining bout expected to start about two hours later.
