WWE chiefs are moving full steam ahead with plans for Sting to make an epic debut with the company against Triple H at Wrestlemania 31, because they are don't expect to be able to call upon The Rock's considerable star power to boost pay-per-view sales.
The Rock has regularly put his blossoming movie career on hold to return to WWE over the last four years, including a pair of main-event matches with John Cena.
Filming commitments will almost certainly stop the living WWE legend from playing any more than a token part in the 2015 event at the Levi's Center, which is part of the reason why Sting got such a prominent role at Survivor Series last weekend.
Sting to get top billing
Wrestlingnews.co cites a report from the Wrestling Observer with its fresh claim that WWE are currently planning to go with a clash of the legends in the main event for Wrestlemania 31, which would mean a simmering feud built between Triple H and Sting over the next few months.
The seeds for that plan were laid at Survivor Series, with Sting making his first ever appearance on WWE programming to interrupt a five-on-five showdown for creative control of the company.
Does this mean The Undertaker will stay retired?
Sting took Triple H out with a Scorpion Death Drop that had huge implications for the man the famous moniker of 'The Game', costing him and wife Stephanie McMahon their positions as masters of the entire WWE roster.
Team Authority were defeated at Survivor Series as a result of Sting's intervention and forced to humiliatingly hand over power on Raw this week, to Daniel Bryan of all people.
WWE resisted the temptation to have Sting appear on Raw and will likely opt for a slow burner of a storyline to build anticipation ahead of a showdown between genuine living legends of the industry, but their clash could well finally mean we've seen the last of the Undertaker.
The Phenom was defeated at Wrestlemania for the first time by Brock Lensar earlier this year and hasn't been since, with retirement rather than another return to the grandest stage of them all now a genuine possibility.
