One almost forgotten rivalry at the World Wrestling Entertainment (WWE) Night of Champions was the highly charged tiff involving Brock Lesnar and the Undertaker.

While all had been quiet leading to the pay-per-view (PPV), the rivalry continues and it will be at WWE Hell in a Cell which will take place at the Staples Center in Los Angeles on Oct. 25.

Remember that Brock Lesnar was the man responsible for breaking the undefeated streak of the Undertaker at Wrestlemania 30 and has been bragging about it ever since.

That was until the Undertaker decided to return at WWE Battleground as the Beast Incarnate was on the verge of reclaiming his WWE Heavyweight title.

The two had been at it since then and the last match (WWE SummerSlam) saw a controversial finish which seemingly saw the Undertaker tapping out but was unseen by the referee. The Undertaker would eventually win the match but without (as expected) much controversy.

So now the two will be at it again and this time in a punishing steel cage which is all but fitting. Will it be the climax to the much publicized feud?

The initial word is that the two would be slugging it out until Wrestlemania 32, but from the looks of it, the rivalry could end at Hell in a Cell (if the WWE chooses to do so).

Lesnar could come out with a win this time around, although nothing is certain for now. Everyone knows that when Hell in a Cell comes to mind, the names of the Undertaker and Kane pretty much sound out.

If Undertaker wins, it could turn out as good as well and somehow leave him some room for retribution seeing that the Beast holds the bragging right of that first loss at Wrestlemania, of course.

Whatever happens, don't be surprised if it ends in another shocking end. On whose favor, though, is something that remains to be seen.
