James Wade missed five darts to reach the quarter-finals before being knocked out of the PDC World Championship 4-3 by world number 78 Ryan Joyce.
The ninth seed, who had apologised for his behaviour during and after victory over Seigo Asada in an earlier round, led 3-2 in sets, only for his finishing to desert him when he needed it most.
His rival took the match into a decider and won the final set 3-1.
Joyce will play world number one Michael van Gerwen in the last eight.
Northern Irishman Brendan Dolan is also through to the quarter-finals in London for the first time after a 4-1 victory over Dutchman Benito van de Pas.
England’s Nathan Aspinall progressed with a 4-3 win over South African Devon Petersen.
