The hoverboard may be the hottest holiday gift this year, but mastering the craze is an entirely different story.
Just ask Mike Tyson.
The boxing champ took a nasty spill when he tried his daughter's Cyboard hoverboard.
Tyson posted the fall to Instagram with the hashtags #knockout and #MikeTysonBreaksBack.
It's not clear what, if any, injuries Tyson may have sustained.
Right before he crashed you can hear his daughter cautioning Tyson saying, "Daddy, I don't want you to fall."
The board Tyson was riding retails between $700 and $800.
Recent hoverboard falls have been connected to dozens of hospital visits on Christmas and even broken wrists.
It's probably best to suggest wearing a helmet and some pads before taking a spin on one.
