Golf in Middle Earth

From the Hobbit:

If you have ever seen a dragon in a pinch, you will realize that this was only poetical exaggeration applied to any hobbit, even to Old Took's great-granduncle Bullroarer, who was so huge (for a hobbit) that he could ride a horse. He charged the ranks of the goblins of Mount Gram in the Battle of the Green Fields, and knocked their king Golfibul's head clean off with a wooden club. It sailed a hundred yards through the air and went down a rabbit-hole, and in this way the battle was won and the game of Golf was invented at the same moment.

Is there any other mention of Golf in Tolkien's work? The existence of Golf seems out of place with the rest of Middle Earth
