The Undertaker’s current WWE contract is set to end soon. When that happens, it’s believed that he’ll sign a new deal with the company. It may not be a normal long-term contract but it will be more than the usual Legends deal that wrestlers like him sign at this point in their careers.
It has been rumored that Undertaker will be back for WrestleMania 32 in Dallas (his home state of Texas), which is also rumored to be his retirement match.
