WWE Fastlane 2019: 5 things that should happen at Fastlane

#5 Brock Lesnar attacks Seth Rollins

Brock Lesnar and Seth Rollins

Brock Lesnar is not scheduled to appear in this Sunday's Fastlane PPV, but considering the number of surprises that we've witnessed lately in the WWE, we can't rule it out.

The Beast is set to defend his Universal title against Seth Rollins at WrestleMania 35, and the build to one of the main matches of the night has had little build to it, owing to Lesnar's non-appearance on RAW or even PPVs.

Following The Shield's match against Drew McIntyre, Baron Corbin, and Bobby Lashley, Lesnar should make his way to the ring and take out Rollins, sending him a huge message to him ahead of their WrestleMania 35 match.

We will most likely see Lesnar on a few RAW shows before 'Mania, and his mind games could begin at Fastlane.
