ROH World Champion Nigel McGuinness suffered an arm injury at last night’s 3/20 ROH event in Elizabeth, PA reports PWInsider. The injury was serious enough that it required ROH to call a doctor to examine him after the event. There was some concern that McGuinness would need surgery as a result of the injury, but that hasn’t been confirmed yet. He was still scheduled to defend the ROH Title against Pro Wrestling NOAH star KENTA in the main event of tonight’s ROH 7th Anniversary show in New York City, NY at the Hammerstein Ballroom.
