Brock Lesnar does not know who Chael Sonnen is

(at 7:50) Jim Rome asked Lesnar his reaction to Chael Sonnen’s trash talk including Sonnen’s dubious claim that he’d “slap you in your face and you wouldn’t do anything about it, Brock.”

Lesnar had a simple retort: “I don’t know who he is. Is he a fighter? I don’t know who he is. I’m serious. Seriously.”
