Kavan Markwood knows how lucky he is to survive a 21-foot fall — that was on video for the world to see.

Markwood, the fan who fell from the bleachers onto the warning track dirt during a Pirates game at PNC Park in April, lay motionless on the ground in a frightening scene.

“I don’t know how I’m alive,” Markwood told “Inside Edition” as he walked around Pittsburgh’s PNC Park for the first time since the incident. “I wake up with pain every day. My arm, I can’t feel my two fingers still. [But] I’m doing better than what I was, that’s for sure.

The grounds crew quickly got Markwood off the field and he was diagnosed him with a broken neck, clavicle, and back after a several touch-and-go days.

The video of Markwood was one of the most viral social media clips of the past few months.

Players for the Pirates and Cubs were distraught over the scene.

“I just hope everyone knows that I fell and I didn’t jump over the railing,” Markwood said. “It was just a tragic accident.”

Markwood, who was 20 at the time of the incident, adds that he also suffered a punctured lung and broke every rib.

His brother, Ethan Markwood, was charged with multiple counts of providing alcohol to a minor in connection with the incident, although Markwood says that the fall had nothing to do with alcohol.

Markwood says he got excited and fell after flipping over the fence.

“Tragic accident,” Markwood said, adding that his “buddy bought him some beers,” according to “Inside Edition.”

Markwood’s girlfriend told police that he only had two beers.
