On WWE Monday Night Raw on February 29, 2016, Dean Ambrose was able to convince HHH to give him a shot at the World Title.
WWE had previously teased a possible HHH title defense at the March 12th “March to WrestleMania” Network special from Toronto. This is a house show that will air on the Network as a bridge between Fastlane and Wrestlemania 32.
Triple H is booked for that show, and thus the match is likely being built up for that show.
WWE is also considering keeping Roman Reigns off of TV until that special for an angle to build heat for the Wrestlemania 32 main event.
This was a WWE.com story that was later pulled about the possiblility:
he Road to WrestleMania is heating up, but on March 12, an event will take place on WWE Network that could completely alter the landscape of The Show of Shows. “WWE March to WrestleMania,” LIVE at 8pm ET/5pm PT.
Just three weeks shy of WrestleMania, WWE World Heavyweight Champion Triple H will defend his illustrious prize for the first time since capturing it at the Royal Rumble. Plus Brock Lesnar, Bray Wyatt, WWE Tag Team Champions The New Day, Sheamus, King Barrett and many more of your favorite WWE Superstars will be scheduled for action.
