UFC fighter Eryk Anders suffered a super GNARLY injury this week ... when he was chopping trees down with a chainsaw, and SAWED INTO HIS OWN FOOT!!
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.
