6 WWE Superstars who could return or debut on SmackDown Live after Royal Rumble

#1. Lars Sullivan

A healthy Lars Sullivan spells disaster for the rest of the main roster

There are several strange reports currently surrounding Lars Sullivan, however, as we have previously mentioned that mental issues are no joke. Lars Sullivan is seemingly poised to be WWE's next big superstar (and I mean literally as well). The former NXT Championship challenger was set to make his debut on Raw several weeks ago, however, his debut eventually got postponed when he suffered an anxiety attack backstage on Raw.

There have been several updates on Sullivan's health since then with WWE COO, Triple H confirming the fact that Lars is seemingly in a better place and in a recent update on Twitter, it was also confirmed that Sullivan is indeed in a better place.

That being said, there is surely a possibility that Sullivan might finally make his main roster debut tonight on SmackDown Live and shock the world. With the likes of AJ Styles, Andrade, and even Randy Orton in need of fresh feuds, I feel Sullivan could possibly step up to the plate and take full advantage of the opportunity presented to him.
