Dave Meltzer of the Wrestling Observer is reporting Sting suffered a serious neck injury during the main event of last night’s WWE Night Of Champions pay-per-view.

According to reports, Sting suffered a legitimate and “significant” neck injury, but not much else is known at this point.

It was originally thought that Sting was injured after he was powerbombed into the turnbuckles by WWE World Heavyweight Champion Seth Rollins during the title match. Sting’s head was seen snapping back during the spot; he was later checked on by the ringside doctor, then Rollins ended up rolling him up as part of the planned finish.
