According to Dave Meltzer on Wrestling Observer Radio, Undertaker was said to be “really hurting” after Sunday’s Royal Rumble PPV. Undertaker had minor hip surgery back in the fall of 2016; word is that Undertaker will need a full hip replacement, but has been trying to put that off until he retires. The minor surgery he had was a temporary fix.
Opinionated View- All the more reason Taker should not be wrestling. And why it was other bull shit people were saying he should win the Rumble.
