NBC concerned about Jimmy Fallon, according to report

NEW YORK -- Last week, Jimmy Fallon was stitched up at a hospital in Cambridge, Mass., after falling — and dropping a bottle of Jägermeister — while receiving the Harvard Lampoon’s Elmer Award for Excellence in Humor.

The incident follows three other "party-guy injuries" in four months, one of them causing him to almost have a finger ripped off in a freak accident. He also chipped a tooth in August.

As a result, The New York Post is reporting that sources say NBC is worried that Fallon's drinking has turned excessive, and while they're not doing anything about it yet, "it's gone from being a whisper to a chatter."

The source said hosting The Tonight Show is a very high stress, lonely job, and that Jimmy is only 41.

“Jimmy Fallon is a highly valued member of the NBC family who is both a tireless worker and an extraordinarily gifted performer,” an NBC spokesperson said in an official statement to The New York Post.
