Gymnast Louis Smith will be out for up to a month after fracturing his finger.
The pommel horse specialist, who won bronze on the apparatus at the 2008 Beijing Olympics, suffered the injury on Tuesday after he stubbed his finger on the high bar.
Smith, 22, who trains at Huntingdon Gymnastics club, told Sky Sports: "I will probably be out for about four weeks, with recovery and getting back into it.
"I could be annoyed but it won't get me anywhere and that will make things worse. I need to stay positive and I am confident I will be able to get back to where I need to be, it's only a little fracture."
Smith tweeted a photo of his right arm in a sling before the picture was then removed.
The injury means the Peterborough-born gymnast looks set to miss out on next month's World Cup competition in China.
However, the London 2012 poster boy does not believe the spell on the sidelines will derail his chances of making it to the Games this summer.
"I'm going to have to train a lot harder, a lot more running around to keep fit so that when I get back to doing gymnastics stuff it is not so much of a hill to climb," Smith said.
