WWE SummerSlam 2015 wasn't the first time The Undertaker collapsed after facing Brock Lesnar

As mentioned above, the feud between the former Hardcore Champion and The Beast Incarnate peaked in 2014 at WrestleMania. After the grueling match, the Hall of Famer caused some concern regarding his health after he collapsed backstage.

In his documentary The Undertaker: The Last Ride, the legend said he got concussed early on the match and can't remember his match against Brock Lesnar. His wife, Michelle McCool, said he didn't know where they were, why they were in New Orleans, or his name until 4 AM the following day. When all of this was happening, Vince McMahon and Brock Lesnar were with him.

Speaking on the Joe Rogan Experience podcast in 2021, the Hall of Famer revealed that medical scans showed that he had an unknown neck injury before facing Lesnar at the event.

Despite the health scares, it's fortunate that The Undertaker ended his wrestling run on his terms and is in good health.
