Also the wwe probably was unsure about his wrist and thought damn "He's injured again", and when he turned out to just have banged it up the took the opportunity to release him before he got hurt again, or hurt somebody.
I can't see Kennedy working indies, because he's so damn injury prone and should he get hurt in the indies, he'll starve while out. I think it will be TNA or maybe he'll try to get into movies.
