And, it's just as gross as it sounds.

TMZ Sports talked to 34-year-old Anders just days after he was forced to seek emergency treatment at a local hospital for the chainsaw injury.

"I was cutting down trees, and of course, I was on the last one, and I'm not a professional or nothing. It was a pretty big tree," Anders says, adding, "and I was cutting it and the tree leaned into the blade, so it kinda got stuck. With my other hand I reached up to push the tree, and I thought the chainsaw would keep cutting."

But, that's unfortunately not what happened.

"I guess I didn't have any pressure on the chainsaw to keep it moving in that direction and it kind of skipped off the tree and bounced off my foot."

Ouch.

How much did it hurt? We asked Eryk.

"I didn't even know I did it. Obviously, I felt the weight of the chainsaw land on my foot. I took a second. And, then the tree fell. So, I had to dodge the tree, so it was a big clusterf**k, all in the snap of a finger."

It goes without saying Anders is one tough dude. Not only is he a UFC fighter ... but he used to be a star on the University of Alabama football team, where he won a national championship under Nick Saban.

Thankfully, Anders was patched up by a doctor at the hospital (he needed 20 stitches) and is already back in the gym (maniac).

But, that's likely the end of Anders's logging career.
