Former World Extreme Cagefighting (WEC) Middleweight Champion Paulo Filho, who's battled countless injuries and personal problems since his heyday in PRIDE FC, has signed with World Series of Fighting (WSOF) and could debut as early as next month in Las Vegas, according to MMA Weekly. "Ely," 34, briefly retired in 2011 after a string of dismal performances, but returned to action with an ugly win over "Ninja" Rua last September (watch it here). Anyone expecting the old Paulo to return? Or did that ship sail back in 2008? Photo by Tracy Lee via Combat Lifestyle
