The Undertaker is still said to be banged up from the concussion he received
during his match with Brock Lesnar at WrestleMania 30. Even though he’s been
working out, he has told those close to him that it’s “not looking good” for
Wrestlemania 31. Fun Fact – ‘Taker has his own personal gym
and full-sized wrestling ring inside his home in Texas. He actually wrestles
against his real-life wife Michelle McCool from time to time.
He’s said to be in bad shape after his injury and his status for the event is
unknown. A decision on whether or not he will compete won’t be made until the
end of the year at the earliest.
