Murschell first appeared in a televised darts tournament in 2017, when he took part in the North American Championship, defeating David Cameron, before losing to eventual winner, Willard Bruguier.
After surviving six match darts from "The Machine", Murschell hit double top to win and set up a quarter-final with Gerwyn Price, which he would go on to lose 8–4.
Dawson's quarter-final run in Vegas secured his spot at the World Series of Darts Finals in Austria, although he wasn't able to compete due to falling ill, and had to pull out of the event.
Following the expiration of his PDC pro tour card, in late November 2019 Murschell announced his intention to move home to Canada to focus on his education.
