Rory McIlroy’s aim was a little off on his last shot.

The pro golfer played The Masters on Thursday when he accidentally smacked a golf ball into the back of his father, Gerry McIlroy’s leg.

During his putt on the 7th hole at the Augusta golf course, McIlroy tried to bend a shot around a huge tree but the ball slammed into his dad instead.

Despite giving the heads up, yelling, “Fore right!” the ball still landed in an unfortunate spot.

In the end, Gerry only suffered a minor limp from the incident.
