The former Love Island contestant, who joined The Only Way Is Essex at the start of the 17th series, tweeted overnight that he'd just been to the hospital emergency room.
"Just left A and E. Got a fractured rib. Hurts to even breathe," he said.
When co-star Georgia Kousloulou asked if he was okay, he replied: "Yeh I'm sweet babe, nothing they can do apparently. Just gotta take it easy!"
He later said it hurt when he coughed or laughed, which made watching last night's episode of TOWIE a tad tricky. "Need to not laugh Coz it hurts me! But tonight's episode of @OnlyWayIsEssex is a blinder! Team Alpha v Team Real."
Jon took part in the Team Alpha v Team Real football match to separate the Essex men from the boys. Unfortunately for him, his Team Alpha lost six-nil. Oh dear.
And the end to his evening wasn't much better as he tweeted: "This rib is killing me! Can't get comfortable Co-codamol needs to kick in!"
Get well soon Jon!
