PWInsider.com is reporting The Undertaker's physical health is becoming a concern for WWE officials.
Reportedly The Undertaker badly damaged the replaced hip he got several years ago in the WrestleMania 28 match with Triple H. The report goes on to say The Undertaker was flying to New York to meet with doctors but now WWE has been paying to fly the doctors to The Undertaker's house in Texas because it's becoming such a frequent process.
The talk as of now is to possibly have The Undertaker work Royal Rumble. He could do a few big spots before being eliminated. The talk is if he was to work at WrestleMania, it couldn't be as an intense of a physical match as he's been known to do.
