EXCLUSIVEHulk Hogan is refusing to let his charred-up hand run wild on his wrestling plans -- TMZ has learned the Hulkster has CONFIRMED he'll appear at TNA wrestling's big pay-per-view event in Boston this weekend.
It's kind of a shock ... considering Hogan's been undergoing daily medical procedures on his hand ever since he burned the holy hell out of it during a boating accident last weekend.
But TNA president Dixie Carter tells us she talked with Hulk ... and the wrestling legend reassured her that he will not only attend Slammiversary XI -- but he's planning on taking part in a fan interaction event the day before ... signing autographs.
Luckily the 59-year old wrestler writes with his right hand ... the one without the disgusting burn marks.
Eat your vitamins and say your prayers.
