Dereck Chisora faces off against Kubrat Pulev in a European title fight on Saturday, but things have started heating up already.
Chisora was hit by a plastic bottle during the weigh-in and ran around the whole room, presumably looking for the culprit, with people imploring him to "calm down Dereck".
If he carries that rage into the fight, which is also an IBF world title eliminator, it won't matter that the Bulgarian has only one defeat in his career.
"Pulev has been on my radar for a while now," said 32-year-old Chisora. "He's a great athlete and he has my respect, but come fight night I'm not messing around. I'm coming to mess this guy up. I'm going to outwork him and out strength him. I'll be all over him from the first bell."
