Agreeing to serve as caddie for friend McIlroy, Horan, 21, took a tumble when performing his duty. The singer was walking with the clubs, carrying the heavy bag of clubs on his shoulder when he slipped and fell to the ground, reported Ace Showbiz.
Luckily he was fine and quickly got back up on his feet. Later that day, Niall took to Twitter to address the embarrassing moment and wrote, "If your walking around augusta, don't step on the pine leaves, slippy as hell Hahahaha! #redfaced (sic)!"
