Former UFC heavyweight champion Cain Velasquez shocked the MMA and pro wrestling world last week when he showed up on WWE Smackdown to challenge Brock Lesnar. The two have real world history together: Velasquez took the belt off Lesnar at UFC 121 in 2010. So to see him in pro wrestling threatening to take Brock’s WWE championship? It’s a nice example of the painful poetic parallels pro wrestling loves drawing with real life. But what’s the deal? Is Velasquez now on the WWE roster? Cain spoke with ESPN shortly after his Smackdown appearance and clarified he hadn’t signed a deal with the wrestling company.
