As noted in the past, a match between Sting and Triple H is considered likely for WrestleMania 31, however recently, another match for Sting has been discussed internally.
The idea of a Sting vs. Seth Rollins match has reportedly been brought up recently, a match that seems like a long shot, but has been talked about.
It’s also worth noting that there has been some rumors going around that claim Rollins could be in the WWE World Heavyweight Championship picture soon. Obviously if that were to happen, the Rollins vs. Sting match would not.
This is the time where those pesky WrestleMania rumors begin and there are constant changes. Please take these rumors with a grain of salt until we get closer to the event.
