Will Wilder retire if Ortiz KO`s him?

He won't be missed.

 

I think he won't, if Ortiz KO's him it will be certainly lucky punch. And in general HW is weak right now,r eally only Joshua can be a threat for Wilder, therefore retirement is meaningless for Wilder.

 

So keep fighting the same guys he's been fighting the last 3 years with a title?

 

He wouldn't quit, he'd take some time out and then try and come back face some weak opponents like Martin has and beg AJ or whoever is champion then for a shot to try and cash out.

 

Surely he has a rematch clause, so you would expect him to rematch Ortiz

 

Nope, rematch all the way.
If he gets bombed out, he'll blame peds and rebuilds against pushovers
