Golfer hits himself in the knee with his own golf ball: video

Three PGA Tour Canada golfers were filming a promotional piece last week when one guy got it all wrong.

J.J.Regan was supposed to hit a golf ball while the other two guys lit the cannon. The idea was to make it look like the ball was fired out of the cannon but Regan caught the ball a little thin and the ball ricocheted off the wall and back into his knee.
