During an interview on The Jimmy Kimmel Show, comedian Eric Andre talked about working on a stunt with John Cena while filming the “The Eric Andre Show” which went wrong.

The stunt had Cena tossing Andre into a shelf which left him with a concussion. The blame wasn't entirely put on Cena as he also noted the crew didn’t prepare the stunt properly.

"John Cena did the stunt right, but we prepped for the stunt wrong. And, that metal shelf came over and clocked me in the head," Andre said ... "And, I got concussed."
Andre says he went to the hospital immediately -- noting, "I had like a Fred Flintstone, like Bugs Bunny [welt] on the side of my head."

The good news ... Andre seems to be okay now and was joking about it with Kimmel.
"They did a CAT scan, and I haven’t been able to speak English since. I memorized this interview phonetically, actually."
