Former UFC Light Heavyweight Champion, Rampage Jackson, is super confident that he could beat up WWE wrestler turned UFC fighter, Brock Lesnar.

TMZ Sports caught up with Jackson outside of 1 OAK in L.A. this week and discussed a potential super fight against Lesnar.

Rampage is a legendary MMA fighter with a 37-11 record.  Brock has a lot less experience in the Octagon, but outweighs Jackson by 60+ pounds.  Jackson says despite the weight difference, he could still beat Lesnar’s ass.
