In the wake of the imminent brand extension, WWE may have to split what looks like the biggest main roster in the history of the professional wrestling company.

If rumors doing rounds are anything to go by, WWE top officials have touched base with some of the former superstars and the list of the names WWE may bring back to the four-sided ring has surfaced online, Sportsrageous reported.

It looks like WWE recently realized that they need two full rosters for the fan-favorite shows: Monday Night Raw and SmackDown, Dave Meltzer of the Wrestling Observer tweeted on Saturday, June 18.

WWE just realized they have to fill two rosters, calling lots of 40+ year old guys to return for the new era.

In addition to the existing WWE superstars and the upcoming NXT draft, top WWE officials are now looking to add superstars who have been around the wrestling ring for quite some time now.

The move stems from WWE's requirement to balance the main roster into three categories of stars. A brand will reportedly boast a roster that includes current superstars, the "New Era" stars and the old-timers who needless to say, still got it.

Check out the list of superstars who are rumored to make a comeback to the World Wrestling Entertainment Inc.

Cryme Tyme
Shelton Benjamin
John Morrison
Carlito
Rey Mysterio
Jeff Hardy
Goldberg
Kurt Angle

Kurt Angle has already expressed his desire to return to WWE in 2015, Forbes reported.

Rumors are rampant that WWE wants "The Only Olympic Gold Medalist in Pro Wrestling History," Kurt Angle to coach American Alpha (Chad Gable, Jason Jordan). Goldberg, on the other hand has already bagged a spot in WWE 2K17 and a comeback to the company as an in-ring performer is imminent.

The high flying Jeff Hardy, however still has a contract with Total Nonstop Action Wrestling (TNA). The top WWE officials will reportedly offer him a deal as soon as he contract with TNA expires this year.

As far as Jeff's brother, Matt Hardy is concerned; there are no indications of the WWE approaching him as well to sign a deal with the company. Matt is currently with TNA.

"The Biggest Little Man," Rey Mysterio and Morrison are still under a contract with Lucha Underground, however the WWE could entice these superstars with a similar deal that attracted Alberto Del Rio.

JTG, Shad Gaspard, Shelton Benjamin, Carlito are all currently wrestling in the independent circuit.
