The Darts Regulation Authority has suspended Dominic Taylor following the failure of a drugs test.
Taylor was tested at a recent Players Championship event and returned a positive sample for a banned substance.
The Chairman of the DRA has confirmed that Taylor is suspended with immediate effect and will face a disciplinary hearing on a date to be confirmed.
As a result, Taylor has been withdrawn from the Players Championship Finals and will be replaced in the draw by Nick Kenny, who will now play Michael Smith on Friday evening.
