A day after the Undertaker came out of nowhere to sabotage Brock Lesnar's title shot at Battleground, the Deadman and Beast were at it again at Monday Night Raw as the two superstars engaged in one of the most chaotic brawls in WWE history.

With both men still fuming in anger, WWE officially announced on Monday that the much awaited grudge match between the Undertaker and Lesnar will take place at Summerslam on Aug. 23 at Barclays Center in Brooklyn New York.

The Phenom made his first appearance in Raw since his feud with Bray Wyatt, and he didn't waste a second to explain why he had to attack Lesnar, who was on the verge of reclaiming the World Heavyweight championship after totally dismantling Seth Rollins from the get-go in their title-match at Battleground.

While he understands that all streaks must come to an end, the Undertaker stressed he just couldn't take anymore the utter disrespect he's getting from Lesnar and his manager Paul Heyman after building himself as one of the greatest performers that ever step in the squared the circle for a quarter of century.

For that alone, the Undertaker wants retribution, and he vows to get it at the biggest wrestling event this summer, at Summerslam 2015.

It's no secret that this Wrestlemania rematch between arguably two of the biggest superstars in the last decade is going to be big in every way. However, several pro wrestling pundits are a bit perplexed about the timing of Undertaker's comeback and his revenge plot against Lesnar - the man who ended his Wrestlemania winning streak over a year ago.

WWE writer Joseph Zucker of Bleacher Report chimed in on the WWE's latest plot twist, which he believes is a significant blow on Rollins and his status the WWE World Heavyweight champion.

"Lesnar vs. 'Taker is obviously a huge match, but it's still kind of surprising WWE is pushing its primary championship on the periphery a bit for one of the biggest PPVs of the year-not that the decision is indefensible," according to Zucker.

The jury is out if WWE's latest gamble will pay off. The Undertaker and Lesnar are already huge superstars in their own rights. There's no need to over-promote this feud no matter how untimely it is, because one way or another, this Summerslam main header is going to be a 'helluva' show.
