Sherrock cited 'unexpected changes to the event' after the prize fund was slashed in half due to poor ticket sales.
The Swedish ace who is now based in the UK plying her trade in county darts for Cheshire is a former semi-finalist in the event and will face Corrine Hammond meaning no change to the draw.
In response to Sherrock deciding not to play in the event, the BDO released the following statement when announcing Pruim's entry into the tournament.
"The BDO would like to wish Fallon all the best with her future darting endeavours and we are looking forward to seeing who will rise to the challenge in 2020 to be crowned BDO World Darts Champion."
It all kicks off on Saturday 4 January and will run until the 12th January, will we get a new champion in both the men's and ladies?
