Kevin Owens is the latest to be subject to such fears. At a WWE live event in Columbia, South Carolina, this past weekend, Owens was up against blood rival Sami Zayn, and it was Zayn who came out victorious thanks to a Blue Thunder Bomb. Referee Charles Robinson threw up the 'X' after the match, and Owens was helped to the back.
Of course, such things could mean nothing more than precaution. No other reports have come out of the show suggesting anything more than a precautionary measure. Even so, Owens has become such a vital part of the main roster in WWE that even the slightest fear he may be injured should be taken seriously.
