Brock Lesnar broke a piece of the Monday Night Raw set during his wild brawl with Samoa Joe

Their main event bout for the WWE Universal title should be epic.

Brock Lesnar and Samoa Joe are set to face off at the Great Balls of Fire PPV in just a few weeks, but the champion and challenger couldn't wait to get after each other any longer than Monday Night Raw.

As Lesnar was making his entrance, Joe attacked him from behind and put him in the Coquina Clutch. After running him into the video board twice, Joe got Lesnar on the ground as other stars had to pull him off.

Judging from their brief battles in recent weeks, their main event bout for the WWE Universal title should be epic.
