"My left leg is the one that I injured," Hill said in a YouTube video released Wednesday titled "The Cheetah Runs Again." "I have no power in my left leg at all. I'm trying to regain all the power back in my left leg," he continued. "My timeline looking, I ain't gonna tell you what my timeline is, but timeline looking real good right now, man." And potential for, never been reported to my knowledge, nerve damage – and is that why his leg still doesn't have power?
