The WWE Universe was on its toes as they awaited to see not only if Brock Lesnar would successfully retain his Universal Championship over Roman Reigns at WrestleMania 34, but if he'd also be leaving the squared circle altogether.

Last week, UFC president Dana White confirmed that Lesnar would be returning to his company, and it only led to speculation that Reigns would pin the Universal Champion - before The Beast Incarnate left the WWE for good.

But in a couple of major twists, Lesnar easily destroyed and defeated Reigns to retain his championship. A day later, WWE announced that they had signed Lesnar to a new contract.

According to Dave Meltzer of MMA Mania, sources are saying Lesnar's new contract is "short-term," and it allows him to fight at least once in the UFC - but it's unknown if he'll be permitted to compete in multiple shows.

Meltzer also reported that Lesnar and WWE chairman Vince McMahon "kept the Wrestlemania 34 result secret from almost everyone, including the top executives and the writing team." This meant that they expected Lesnar to lose the championship to Reigns, and that the former would walk out of the WWE and move onto the UFC once again.

WWE also announced that Lesnar will defend his championship against Reigns at the Greatest Royal Rumble pay-per-view show on Apr. 27 in Jeddah, Saudi Arabia. But that may not be Lesnar's only big fight over the coming months.

Kris Zellner of Between the Sheets also reported that rumors are floating around that Lesnar will face Bobby Lashley at SummerSlam. The latter returned to WWE on Monday Night Raw, after spending 10 years away from the company.

While we don't know what's in store for Lesnar's long-term future, we at least know that he's not done in WWE just yet, and that a return to the UFC will be happening before long.
