The Tribal Chief noted that he did not wish an injury on anyone and would have loved to beat Rollins up all by himself instead."They got a lot of serious problems going on. The man that Paul Heyman, my former Wiseman chose to ride with, doesn't look good, man. I don't really want to speak on that because I believe in that karma. So, I wanna see how that plays out. Obviously, we have not been on good terms for a long time. I don't wish injury on anybody because I'd rather him be here so I could whoop his a** myself. I prefer a healthy little bi**h, so I can smack him up," he said.You can check out the video below for Roman Reigns' comments:It will be interesting to see when Seth Rollins makes his return to WWE programming.
