- Regarding the injury that Sting suffered at WWE Night of Champions, we do know that Sting's neck is not broken. He was taken to a hospital after Night of Champions and was able to walk but was not well. An MRI he underwent did not show any fractures to the neck, according to Wrestling Observer Radio.
Furthermore, PWInsider notes that there was also some concern within WWE of a spinal injury. We don't know what the prognosis on Sting is yet but it's possible he could have wrestled his last match, at least for a while. WWE officials will likely be leery of putting Sting back in the ring.
As noted, Sting did not appear on Monday's RAW because he went home to Dallas to rest and recover.
It was also noted on Wrestling Observer Radio that the finish that happened with Sting vs. Seth Rollins for the WWE World Heavyweight Title was the planned finish but they just went to it quicker because of Sting's injury.
