Nile Wilson will miss three significant events after undergoing neck surgery.
The 23-year-old from Leeds, one of Britain's biggest stars, has been suffering from pain in his arm caused by a large disc bulge and underwent what has been described as a successful operation earlier this week.
As a result, he will miss the British Championships, the Gymnastics World Cup and the European Championships but will hope to return for the World Championships in Stuttgart at the end of the year.
Wilson said: "I'm feeling very, very positive. I'm recovering well from the surgery and focusing for the first two weeks on rest as I have a sore throat and a sore neck.
"Everything looks like it's gone well and for me it's all about remaining positive and then, when rested, focusing fully on my rehab going forward."
Wilson won a bronze medal on the high bar at the Olympics in Rio in 2016 and collected five medals at last year's Commonwealth Games, including gold in the individual all-around competition.
