MMA Weekly confirmed an initial Tweet from the Team Trojan FreeFighters camp late last night.

Looking to play spoiler (again) is Cope, who got a lot farther than people anticipated on season 13 of The Ultimate Fighter (TUF).

Cope was invited back to compete at the June 4 live finale where he secured a unanimous decision win over former cast mate Chuck O'Neil.
