Dave Grohl has six metal screws in his leg.

The Foo Fighters frontman fractured his limb when he fell off stage during a show in Sweden last week, and underwent surgery on Monday (15.06.15) during which the metal bolts were placed in his leg to encourage a full recovery.

He said: ''So... here I am, recovering with 6 metal screws in my leg, thinking about a lifetime of holding up TSA lines from here to Kalamazoo....damn. (sic)''

However, the 46-year-old rocker confessed he is still unsure about how the injury will impact him long-term.

He continued: ''My doctors have advised me to lay low for a while. The most important thing now is for me to recover from the surgery, to keep my leg elevated so as to keep swelling down and prevent any infection/complication that could do long term damage. I'm not out of the woods yet, folks.''

The 'My Hero' hitmakers have now cancelled a string of scheduled European performances including two dates at London's Wembley Stadium and their headline slot at Glastonbury Festival next Friday (26.06.15), but said the accident has given them ''a new sense of appreciation'' for their talents.

He wrote on the band's website: ''All in all, it was without a doubt the single most bizarre Foo Fighters show in the entire 20 years of being a band. Hands down. What seemed like a tragedy at first turned into a triumph, and we all walked away with a new sense of appreciation for what we've got.''

Meanwhile, Glastonbury organiser Emily Eavis has sent her well wishes to Dave, and insisted they have a contingency plan in place for a replacement headliner, with an announcement expected imminently.
