Rumor Roundup (Sept. 23, 2015): Sting injury, Brock Lesnar vs. Undertaker, WrestleMania 32, 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:

• It's been noted by PW Insider that the fear is Sting suffered a spinal injury. What's more WWE will almost surely avoid booking him for matches in the future, so his in-ring wrestling career is likely over.

• According to Dave Meltzer, unless Vince McMahon changes his mind, Brock Lesnar vs. Undertaker is no longer the plan for WrestleMania 32. The match at Hell in a Cell will be the blowoff match.

• That could mean that we're finally getting that Brock vs. The Rock match WWE has long wanted to put together.

• It's looking like Charlotte's first title defense will be against both Nikki Bella and Paige at Hell in a Cell.

• According to WrestlingDVDNetwork.com, WWE could be releasing an Eric Bischoff DVD set in 2016.
