Once in a while, we hear surprising news about WWE - reports of possible returns and reunions included. But one such rumor these days is set to be big if proven true. Word about a possible return of Triple H and The Undertaker has been spreading around like wildfire.

As "Clash of Champions" is on its way this Sunday, there is speculation that Triple H would appear during the event to accompany Mick Foley and his wife, Stephanie McMahon. It's actually been quite a long while since Triple H was seen on any WWE show.

He's been on a long rest after his defeat to Roman Reigns, which cost him the WWE World Heavyweight Championship in WrestleMania 32. But last week on a Raw event, The Game shocked all WWE fans when he returned to the ring during the Fatal Four-Way match, with Reigns losing the contest and ensuring that Kevin Owens wins the WWE Universal Champion over Seth Rollins.

According to The Inquisitr, a glimpse of Triple H's return last week is an indication that he will have an active role in the company. WWE Clash of Champions will be his opportunity to reinstate himself and reclaim his authority over the company. Reports also say that his return to the ring will not happen the soonest possible time  with WWE production planning to hold his return to WrestleMania 33 against Seth Rollins.

The same goes for The Undertaker. Earlier reports say that his return will likely be on the grandest manner possible. As per Christian Post, The Undertaker will stick for a while for one more match before retiring and that might happen at WrestleMania 33. It will also give him the chance to prove and be in the conversation on who's the greatest WWE superstar of all time.

Rumors have it that among the possible opponents for The Undertaker would be Goldberg, Brock Lesnar or Sting, or it could also be a Fatal Four-way match between them. If speculations are true, we could see Triple H and The Undertaker in WrestleMania 33 on April 2, 2017, at Orlando, Florida.
