5 Startling changes WWE made in SmackDown and RAW in 2019

#2 The MMA bigwigs -- Ronda Rousey and Brock Lesnar -- are gone... at least for the time being!

Ronda Rousey and Brock Lesnar aren't likely to perform for WWE in the ensuing weeks

"The Beast Incarnate" Brock Lesnar's long and tyrannical reign as the WWE Universal Champion finally came to an end at WrestleMania 35, courtesy a well-timed low-blow followed by a hellacious Curb Stomp by Seth Rollins.

The vast majority of professional wrestling experts believe that the reason behind WWE booking Lesnar to drop the Universal Title to Rollins at WrestleMania 35, is that Lesnar is likely to compete in an MMA fight this August.

Lesnar is likely to fight reigning UFC Heavyweight Champion Daniel Cormier for the latter's title in a 5-round Mixed Martial Arts bout at UFC 240.

On the other hand, just like former UFC Heavyweight Champion Lesnar; ex-UFC Women's Bantamweight titlist Ronda Rousey too isn't likely to compete in a WWE ring. However, unlike Lesnar, Rousey isn't returning to the UFC's famed Octagon for an MMA fight.

Instead, Rousey is rumored to be dealing with an injury which she sustained during her Triple Threat "Winner Takes All" match against Charlotte Flair and Becky Lynch at WrestleMania 35.

Considering all of that, it's very important to note how two of RAW's biggest attractions are likely to be absent for several weeks in a row -- thereby giving the brand advantage to SmackDown Live...Speaking of which...
