4 Times Brock Lesnar lost his cool

#2 When he threw a legitimate punch at Braun Strowman at Royal Rumble 2018

Strowman learned it the hard way!

Brock Lesnar defended the Universal Championship against Braun Strowman and Kane in a triple threat match at Royal Rumble 2017. Lesnar's Universal title reign counted 301 days at the time and was on his course to beating CM Punk's 434-day title reign.

During the match, Strowman landed a few stiff knees on Lesnar's ear which enraged the Beast Incarnate. Lesnar took things into his own hands and threw a legitimate punch at Strowman which knocked down the Monster Among Men to his knees.

Lesnar was audibly yelling "Slow the f*** down" at Strowman after landing the punch. Strowman learned it the hard way not to have his emotions prevent him from being safe in the ring.

WWE banned the use of closed fist punches as it could cause severe damage to the receiver. Other superstars would’ve got in trouble for doing that, but Lesnar got away with it like it never happened.
