'Survivor' Villain Jonny Fairplay -- I Broke My Finger Playing Kickball

"Survivor" villain Jonny Fairplay got tossed in the air by an angry buff guy Thursday and broke his finger in the process -- only this time, Danny Bonaduce wasn't involved.

Jonny says he broke his ring finger this week playing in an adult kickball league ... after a large man bum rushed him at second base, knocking Fairplay high into the air.

The "Survivor" star got checked out by a doctor after the game -- they said he also tore a tendon in his middle finger -- but for now he won't need surgery, just a splint and some tape.
