The Undertaker has reflected on the concussion he suffered at WWE WrestleMania 30, explaining why he believes a bump he had endured countless variations of throughout his career affected him so severely that night.

The WWE Hall of Famer was injured during his historic match against Brock Lesnar at WrestleMania 30 in April 2014. Lesnar famously ended The Undertaker's undefeated WrestleMania streak, but behind the scenes, the veteran was in serious enough condition that he was taken to hospital before the event had concluded.

More than 12 years later, The Undertaker still has no memory of competing in the match.

Speaking on his Six Feet Under podcast alongside Paul Heyman, Undertaker discussed the moment he believes the concussion occurred. Looking back at the footage, however, he does not consider the bump particularly severe compared with some of the punishment he absorbed during his lengthy career.

“I think that’s somewhere where it happened. But when I watch it, it’s like, I’ve taken far worse bumps and popped up.”

Rather than blaming one unusually dangerous impact, Undertaker believes his age and increasingly limited wrestling schedule played a significant part.

“I think what happened is, it’s getting late in my career, and at that point I’m only working a couple of times a year, and it’s Father Time catching up with me. When your body’s not used to that trauma, you just don’t take it as well.”

Paul Heyman offered another perspective, pointing towards the accumulated punishment wrestlers and combat sports athletes experience throughout their careers.

“It’s also the number of dings that you’ve taken over the years.”

Heyman then recalled a conversation he once had with former UFC star Ronda Rousey concerning her 2015 defeat to Holly Holm at UFC 193.

“Out of nowhere, she just turned to me and said, I have to tell you what really happened between Holly Holm and me. ‘ And I had never brought that subject up.”

According to Heyman, Rousey explained that an accident during her childhood had left her particularly susceptible to being caught in a certain area. She believed that vulnerability became significant during the Holm fight.

“She started talking about how, when she was a kid, an accident happened, and it knocked her out cold. And because of that, she was always vulnerable to getting clipped just on the right side. And she took the clip in the first round. She was out, but on her feet, because that was her training. Just fight it through, fight it through. Ignore it. Let’s just go. And everything was on muscle memory.”

Heyman added:

“There comes a time that when you’ve taken so many hits, it’s not that nuclear hit that wipes you out.”

Undertaker Has No Memory Of WrestleMania 30 Match
The severity of Undertaker's concussion has been documented by the man himself on several occasions.

His memory reportedly did not begin returning until approximately four or five in the morning following WrestleMania. During his hospital stay, medical staff repeatedly asked him his name and age at intervals of around 10 to 15 minutes.

Of the people around him, Undertaker has said the only two individuals he recognised were his wife and then-WWE Chairman Vince McMahon.

He has also explained that he essentially completed the remainder of his match against Lesnar through instinct and muscle memory. Despite subsequently watching footage of the contest, none of it has triggered any memory of actually competing in it.

His final clear memory from WrestleMania 30 reportedly comes from around 2pm that afternoon, several hours before he stepped inside the ring.

The experience also affected Undertaker psychologically as he prepared to wrestle again.

His next match came one year later against Bray Wyatt at WrestleMania 31. Undertaker has previously revealed that Triple H discovered him crouched in a corner of the Gorilla position shortly before his entrance and reminded him not to forget who he was.

Those words clearly remained important to Undertaker, who later thanked Triple H for them during his WWE Hall of Fame speech.

Doctors ultimately cleared Undertaker to continue wrestling without restrictions, although he was warned that another similar incident would require a much more serious discussion about his future.

Undertaker was 49 years old when he faced Lesnar at WrestleMania 30. He continued wrestling for another six years before retiring in 2020, although his appearances became increasingly sporadic during the closing stages of his career.

He competed in only eight more matches following WrestleMania 30, averaging little more than one match per year, reinforcing his belief that his body was no longer regularly conditioned to withstand the physical trauma of professional wrestling.

The Undertaker has since moved into a new chapter of his wrestling career and currently works on the creative side of AAA.

WWE's approach to potential head injuries has also evolved considerably since 2014. Medical personnel stationed at ringside now have the ability to stop matches when necessary, regardless of whether the wrestler wants to continue, while referees are expected to immediately escalate concerns involving possible head trauma.

Je'Von Evans provided a recent example during WWE Raw in January. After telling the referee he was seeing stars, Evans reportedly asked her not to summon medical assistance. The match was nevertheless stopped.

Brock Lesnar, meanwhile, confirmed his retirement this month following his defeat to Oba Femi at WWE SummerSlam, bringing his career to a close more than 12 years after the unforgettable WrestleMania encounter that ended The Undertaker's legendary streak.
