He had apparently been spotted celebrating his performance at the awards with a couple of well-deserved glasses of champagne, but unfortunately for the Irish TV star, he'll now have to keep away from the booze when he hosts the Eurovision Song Contest in Russia on May 16.
Graham told the BBC: "When I opened my pain medication today it said to avoid alcoholic beverages for four to six weeks - so I'm going to be sober in Moscow."
The comedian went on to explain how the accident happened: "I got home and fell down my stairs and broke two ribs.
"I've been to hospital and was given horse-tranquillising pain-killing medication. But there's nothing they can do about broken ribs."
