Former finalist Kirk Shepherd suffered a first-round exit at the hands of 13th seed Wayne Jones in the PDC Ladbrokes.com World Darts Championship at Alexandra Palace.
Shepherd won the opening set but but an erratic display thereafter saw him crash out 3-1.
The 24-year-old reached the final two years ago, but he was only granted a place in the main draw this year after Australian Rob Modra failed to gain the required visa in time to allow him to fly to London.
Danish qualifier Per Laursen sprung a surprise when he beat three-time world champion John Part 3-0. Part was clearly struggling with illness and while he managed seven 180s, the 32nd seed was below his best as he bowed out without taking a set.
The Dane, who qualified for the main draw by beating Boris Krcmar, faces the daunting task of meeting world number one and defending champion Phil Taylor in the next round.
Elsewhere, Robert Thornton recovered from a mid-match stumble to overcome Nigel Heydon 3-1 and Wes Newton enjoyed a far easier night as he swept American Darin Young aside 3-0.
