As seen on Monday's WWE RAW, Dominik Mysterio was rushed to a local medical facility after receiving a devastating Cervical Clutch by Veer Mahaan. 

Noticeably absent was Dominik's father Rey Mysterio, who himself was actually dealing with a medical issue. Dave Meltzer on the latest Wrestling Observer Radio noted the following: 

"It was a medical issue.

It’s not false advertising or they changed their mind. He was unavailable tonight."

We wish Rey Mysterio well.
