Rory McIlroy is playing in the WGC-Accenture Match Play Championship at Dove Mountain in Arizona this week. He beat Boo Weekly 3 & 2 yesterday.
On the 15th hole, McIlroy was faced with an awkward shot as his ball was placed next to a stone. Unable to move the stone, he took a swing. The resulting shot was a bit wild and hit a fan causing him to fall into a Jumping Cholla cactus.
Luckily for the fan, this was America, so for some reason loads of people were carrying knives which they used to remove the pieces of cactus.
