There's a chance it will, if not, the potential growth will just be transferrred to rest of the cola and it wil;lbe fatter and shorter than it would have been, your final harvest will be the same.its brown but i still see a little green left insides of many of the young upcoming leaves..
I had something like this happen to one of my plants once and actualy chopped off the burnt tip kind of like topping it and what happened is exactly what frmrboi say. The bud started to blow up it was a shorter but fatter nugg it grew kind of like a soft ball LOL.
