Jimmy Fallon Canceled Friday's TONIGHT SHOW After He 'Almost Ripped' His Finger Off

Jimmy Fallon is one of the happiest people on television. It takes a lot to get him down. Add a horrific finger injury to the very short list of things that can get him down. Fallon had to cancel Friday's Tonight Show after an injury sent him to the hospital.

So what happened to Fallon's hand? Too much hashtagging? Violent thumb war against Justin Timberlake? Turns out a simple trip at home wound up causing a ton of damage.

Tripped and caught my fall (good thing)! Ring caught on side of table almost ripped my finger off (bad thing).

The Tonight Show is off next week, so Fallon will have plenty of time to recuperate.
