#3. Is this the end of the road for Rey Mysterio?

It looks like it's going to be a while before we see Rey Mysterio back in a WWE ring. For all we know, Extreme Rules 2020 may just have been the end of the road for him. Seth Rollins managed to gouge Mysterio's eye out and looked away in disgust after realizing what he did.
Mysterio was then escorted out by the staff and his son Dominik, who has had an increasing presence on Monday Night RAW. It's no secret that Dominik is training to become a wrestler, having trained under the veteran Lance Storm for quite a while.
He's also gotten involved with his father Rey Mysterio in his feuds against Brock Lesnar and Seth Rollins and all of that has led to the inevitable conclusion that his WWE debut is drawing nearer. At this point, it's just a matter of 'when' and not 'if' he debuts.
While we can't imagine it happening just yet, don't be surprised to see him confront Seth Rollins all by himself on RAW.
