Wrestlemania hasn't even taken place and Roman Reigns is already being groomed for another storyline against a not-so new nemesis – the Big Show.

With rumors running wild that Reigns will come out victorious at Wrestlemania, it seems that the former Shield member will be rekindling an old flame with the biggest athlete in the WWE today.

Both Reigns and Show have a history of disliking each other, one that can be traced back to the Tables, Ladders and Chairs match where Reigns interfered and hit the Big Show with his patented Superman punch.

And all this takes place on April 6 during the WWE European tour where Reigns will face Show in a street fight.

With all these advanced speculations, could it be safe to say that it will be goodbye to Brock Lesnar? It will be recalled that Lesnar's contract with the WWE is still in turmoil and with word that Reigns will come out on top, it seems that Wrestlemania 31 will be the last hurrah of the Beast Incarnate.

As for Reigns, having Big Show for his first opponent after latching on to the WWE title may not be that interesting for fans. And hence, rumors add that this feud will be short-lived.

On that note, we may see other stars such as Seth Rollins, Randy Orton or even John Cena eventually headlining a storyline with Reigns after his feud with Show comes to an end.

This is with the understanding that Lesnar is out of the WWE scene. Should Lesnar's defeat simply be a detour, well, expect their feud to headline the WWE once more.

So it all depends on the fate of Lesnar as his contract with the WWE seems to be in question though there are rumors that Vince McMahon may eventually fire him right there and then at Wrestlemania 31.
