Rumor Roundup (Oct. 18, 2017): Undertaker return, Neville, Jinder Mahal injury, more!

Speculating on the rumors surrounding pro wrestling is a favored pastime of many fans, perhaps second only to actually watching the matches. In this daily column, we take a look at the latest rumors being churned out by the pro wrestling rumor mill.

Important reminder: Rumors are just that -- rumors. None of this has been confirmed as legitimate news or fact, it's just circulating around the pro wrestling rumor mill. Remember, take it all with a grain of salt.

Rumors for the Day:

• According to Wrestling Inc, there's speculation that Undertaker could be returning for a match at Survivor Series teaming with Kane against The Shield.
• Although WWE still hasn't mentioned it and initially denying as much to some media outlets, all signs points to Neville having quit the company.
• Jinder Mahal told ESPN he is not dealing with a shoulder injury, as had been rumored and reported.
• In response to an interview Triple H's nutritionist, Dave Palumbo, gave saying WWE wrestlers are allowed hormone replacement, the company sent out a statement that approximately 7-percent of talent have exemptions due to "certain medical conditions." Dave Meltzer later noted on Wrestling Observer Radio that 14-15 people have a Therapeutic Use Exemption.
• Per Dave Meltzer, Kenny Omega didn't have the IWGP US title at Global Wars due to a mix up with NJPW, and there's no bigger story there.
