The combination features spicy Buffalo sauce, blue cheese sauce, thick-cut applewood-smoked bacon, and shredded lettuce along with your choice of bun and protein.
The option has been sighted in the Green Bay, WI area as well as in central Pennsylvania.
It wouldn't be the first time that McDonald's has offered a Buffalo sauce on a sandwich. Back in 2013, they introduced a Buffalo Ranch McChicken as a value menu item although it was eventually discontinued.
The combination could serve as a spicy follow-up to Sriracha.
