A representative for the singer said in a statement to The Associated Press that Iglesias was 'semi-treated' after the accident at the side of the stage to stop the bleeding on Saturday night. He was advised to end the show but went on to perform for an additional 30 minutes.
'During the show a drone is used to get crowd shots and some nights Enrique grabs the drone to give the audience a Point of View shot. Something went wrong and he had an accident,' the statement read.
While the drone hovered jut above him, he was jumping and clapping into its mounted camera, urging the audience to do the same.
He then reached up with his left hand and holds the drone before adjusting the camera with his right.
But when he does it a send time, his right hand gets pulled into the blades and he suddenly tosses the drone to the ground like it was an animal that had just bitten him.
The screams of those close enough to realise what had happened can be heard in the video.
Whether through serendipitous timing or a swift thinking stage technician, the confetti cannons immediately discharge, giving the Spaniard a few moments to lick his wounds behind the curtain of fluttering white.
Iglesias' show for 12,000 fans is part of his Sex And Love World Tour. His website says his next show is in July in Mexico City.
Fans claimed after the incident the singer attempted to draw a heart on his T-shirt using his own blood - with surprisingly artistic results.
Most witnesses sent well wishes and get well soons to the singer via social media, although many more questioned the wisdom of plucking a machine propelled by rotary blade from mid air.
As well as worry (and bewilderment) the reaction on Twitter was mainly one of respect, that the performer didn't cry off midway through the concert and soldiered on instead.
