The Australian lost his position in the as a result of the many upsets at the 2019
PDC World Darts Championship. The defeats of Gerwyn Price, Ian White and Dimitri van den Bergh for Nicholson. Instead of making a new attempt at the Q School, Nicholson decided to take a sabbatical, he told . "My decision is to not go to Q School in about a week's time. I just don't feel like I'm good enough at this point in time to get through Q School.'' "I don't want to go there and be absolutely flogged and see my confidence wither even more. There were times in 2018 where I played really well, especially around May/June time but I think I need a little bit of time away to try and find a formula to almost get my invincibility factor back, because I don't have that right now.'' "I need to find out what was going right in 2010, 2011 and 2012 as opposed to the last few years where I've had a period of mediocrity and I'm not prepared to live with that.'' "It's not one of those times where I'm saying I might come back in 2020, I am going to Q School in 2020. If there was a form for me to sign right now, I would. It's just a case of doing different things in 2019. Q School has come a bit too quick and we'll work on the game, work on the head and go forward in 2020."
