Tyson Fury picked up a 1,000 euro bar tab for England fans in France after joining them in a sing-along ahead of the last-16 clash against Iceland in Nice.
A shirtless world heavyweight champion was caught on video celebrating with fans, just days after his title re-match against Wladimir Klitschko was postponed due to injury, and he seemed to be enjoying himself.
Fury later posted the bill for his round on Twitter, boasting that he had bought 200 Jagerbombs, while other posts on the social networking site also showed him handing out drinks to fans in a bar.
Fury had been due to fight Klitschko in Manchester next weekend, but it was announced late last week that the fight would be postponed after the 27-year-old suffered a sprained ankle in training.
Earlier on Sunday, Fury's promoter Hennessy Sports denied claims made in the Sunday Mirror which alleged traces of a banned substance were discovered in a sample taken from the world heavyweight champion last year.
A statement read: "We are baffled by today's story in the Sunday Mirror. Tyson Fury absolutely denies any allegation of doping. He looks forward to recovering from his injury and defending his titles against Wladimir Klitschko in October."
