Watch: Dustin Johnson’s drive in Saudi Arabia drills a volunteer (who drops like a rock)

Dustin Johnson, who shot a 67 in Thursday’s opening round, scorched a drive long and left on the 10th hole. The result is painful to watch.

One thing’s for certain if you’re working a professional golf tournament — make sure you keep an eye on those teeing off on the hole you’re working.

That advice was lost on a volunteer at the Saudi International who wasn’t watching when World No. 1 Dustin Johnson pulled out his booming driver during Friday’s second round of European Tour action.

Johnson, who shot a 67 in Thursday’s opening round, was playing well again through the front on Friday when he scorched a drive long and left on the 10th hole.

A volunteer working the event was struck in the back and dropped immediately after being hit.

Fortunately, the volunteer popped right back up and seemed OK, although the commentators reminded us that this might leave a mark.

“You can take away the pain, but you can’t take away the swelling.”

There’s no official word yet on his condition.

As is to be expected, this led to the Twitterverse erupting.
