The minor-league team Gateway Grizzlies of the Frontier League will begin selling a concessions item that is not for the calorie-conscious, ESPN reported.

"Baseball's Best Burger," as the Grizzlies call it, will consist of a hamburger topped with cheddar cheese and two slices of bacon — all between a "bun" made of a sliced Krispy Kreme Original Glazed donut.

The burger is not for the faint of heart — literally — and will contain roughly 1,000 calories and 45 grams of fat.

"We have had the opportunity to bring in a new concession item for the past two seasons and each of them have been very successful," Grizzlies general manager Tony Funderburg told ESPN.

Funderburg, who said he has eaten at least 10 of the creations, claims he got the idea after reading about a restaurant in Atlanta with a similar sandwich, ESPN reported.

Funderberg said the team hopes to sell 100 to 200 of them a night at $4.50 each. The burger will only be available inside the stadium gates, according to ESPN.

Two years ago, the Grizzlies created what they called "Baseball's Best Hotdog" — a frank with two strips of bacon, onions, sauerkraut and cheese sauce. Then, last year they debuted the "Swiss Brat" — a bratwurst sausage with a slice of Swiss cheese in the middle of it, topped with sauerkraut.

"Baseball's Best Burger" follows in the tradition of other great sports-related sandwiches, including the Roethlisburger. Created in 2004 in honor of the Pittsburgh Steelers young quarterback Ben Roethlisberger, it's sold at a place called Peppi's and includes beef, sausage, scrambled eggs, onions and American cheese, according to ESPN.

The independent club, located outside St. Louis in Sauget, Ill., is in its sixth year of operation.
