SummerSlam 2020: 5 stunning ways Dominik Mysterio can upset Seth Rollins 

#2. Rey Mysterio returns to help Dominik

Rey Mysterio and Seth Rollins

Rey Mysterio's big issue right now seems to be that he hasn't signed a WWE contract just yet. Tom Colohue had an interesting report before the official announcement of the match and said that Rey Mysterio's contract status depended on Dominik's match:

"That really depends on if Rey Mysterio signs a new deal. It's also possible that we could see Dominik Mysterio vs. Seth Rollins in a singles match, but that would be done as a way to convince Rey Mysterio, by saying that here, 'we're pushing your son'."

It turns out that this was true and that this was a great way of possibly persuading Mysterio to sign a new contract. For all we know, Rey Mysterio might have already signed a new contract and could simply be held back for a surprise SummerSlam return.

Either way, this seems to be the best-case scenario. It's hard to imagine Dominik having his first match in WWE without any involvement of his father Rey Mysterio. It would make for a great SummerSlam moment.
