TMZ Sports is currently reporting that Sting suffered not just one, but "several" injuries during his WWE World Heavyweight Championship match against Seth Rollins at Sunday's Night of Champions event. Their report also states that, as previously reported by multiple sources, the most serious injury appeared to come after Sting was powerbombed against the turnbuckle, which caused a neck injury.
It was further noted by TMZ "per their sources" that Sting's neck injury was reportedly so serious that doctors were not able to give any kind of a long-term prognosis.
In addition, Sting underwent a CAT scan following Night of Champions, which revealed that he suffered no fractures. The report further states that Sting was released from the hospital this afternoon and was able to walk out on his own, but was said to be in "significant pain."
