An amateur golfer survived falling in a sinkhole in Illinois on Friday.

Mark Mihal was playing at the Annbriar Golf Course in Waterloo when a sinkhole opened up beneath him while on the 14th hole.

The 43-year-old mortgage broker and co-founder of suffered from a dislocated shoulder after a sudden drop into the earth.

Mihal recounted his story on his website saying that he was standing on the course and then he was down.

"I was underground ... I felt the ground start to collapse and it happened so fast that I couldn't do anything," he said. "I reached for the ground as I was going down and it gave way, too."

The sinkhole was 18-foot deep and 10 feet wide which created a large enough opening to swallow Mihal whole.

He added that the situation got scarier as he continued down the hole.

"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," Mihal said.

Immediate rescuers were at first afraid to attempt to get Mihal in fear that the ground would open again.

He was eventually brought back to the surface with the help of his friend Ed Magaletta who bravely climbed down the hole to tie a rope around Mihal for people above to help pull him out.

Geologist Philip Moss told The St. Louis Post-Dispatch that sinkholes are common in the area due to the limestone bedrock's erosion from rainwater. Moss added that the depression in the ground is usually visible but that Mihal "was in the wrong place at the wrong time."

Mihal was quoted by ESPN with his regards on the course and any chance that he would return to play.

"It's a great course. I love the course," Mihal said, having played at Annbriar a couple dozen times over the past decade. "But I would have a tough time probably walking down that hole again."
