The "Hero" hitmaker was onstage in Tijuana, Mexico when he reached out to catch a drone, which he uses to capture video footage at his shows, but the stunt went wrong as the device slashed his fingers, reported Contactmusic.
Iglesias, 40, subsequently flew to Los Angeles to see a specialist and he was booked in for the surgery.
"Thank you to all your concern and good wishes. Enrique is currently undergoing reconstructive hand surgery today... We appreciate your thoughts and prayers," a statement read.
