Ulang would have influenced the outcome of the game for gambling purposes. The Filipino lost 2-0 in sets to Kevin Simm in the preliminary round of the 2017
PDC World Darts Championship. The DRA had started an investigation to a possible
match-fixing case due to a suspiciously high number of bets during this match.
'The Slayer' was interrogated by the disciplinary committee on May 23 and suspended by the Disciplinary Committee three months later. He then received a seven-year suspension. Additionally, Ulang was ordered to pay a contribution to costs in the sum of £2,500.
