Suffolk star Ed Sheeran says doctors told him to cancel shows - or risk not being able to play guitar again - after breaking both his arms.
The singer-songwriter originally hoped to battle through the pain during upcoming performances in Asia.
Sheeran crashed his bicycle as he careered down a steep hill in Suffolk.
He broke both arms and a rib - but revealed to The Jonathan Ross Show that he did not realise the severity of his injuries until the next day.
In an interview which will air on ITV this Saturday (October 21), he explained what happened.
After finally getting the medical help he needed, the songwriter was then faced with the prospect of cancelling some of his upcoming shows to avoid any permanent damage.
Despite only injuring himself on Monday, The Castle on the Hill singer hopes to be back to full fitness within four weeks.
The bike crash is just the latest in a series of accidents for Sheeran, who admits he is "quite a clumsy guy".
He told Ross how he had needed 12 stitches in his hand in 2013 after playing drums at 4am with two beer bottles in his hand.
The singer also "put my foot in a boiling geyser in Iceland" and "had my face cut open".
The Jonathan Ross Show airs on Saturday at 10.20pm.
