(CBS) A sinkhole strikes again.

While a St. Louis, Mo. man was golfing with his usual foursome last Friday on a golf course in Waterloo, Il., something incredibly unusual happened.

The man was swallowed by the earth. Yes, he fell into an 18-foot sinkhole on the 14th hole.

Here’s the story from his wife:

My husband, Mark Mihal, co-founder of golfmanna, went out to play a familiar course in Waterloo, Ill., with his regular Friday foursome. He was having a great round and lots of laughs with his buddies. They were in the fairway on No. 14; Mark had already hit his second shot when he went to check out the distance for his playing partner, Mike Peters, who was getting ready to hit. Mike had his back to Mark and when he turned to say something to him, Mark was gone.

Mike could hear Mark moaning and ran in the direction where he had been standing just a few seconds earlier. It was immediately clear what had happened; the ground had caved in and Mark had fallen into the earth – 18 feet underground.

“I felt the ground start to collapse and it happened so fast that I couldn’t do anything,” Mark said later. “I reached for the ground as I was going down and it gave way, too. It seemed like I was falling for a long time. The real scary part was I didn’t know when I would hit bottom and what I would land on.”

After about 20 minutes, the group was able to get Mark out of the hole.

Sinkhole 0, Golfer 1.
