James Wade will miss the next four PDC tournaments after being suspended following a breach of the Darts Regulation Authority disciplinary code.
The world No 5 misses the Sydney Darts Masters later this month, the European Tour event in Hildesheim, Germany and two Players Championships in Barnsley.
He was found to have "acted in a manner which may reasonably be considered to injure or discredit the DRA or bring the game into disrepute".
Wade, 30, is free to return at the German Darts Masters in September but the troubled star has not won a televised PDC tournament since in sixth, the UK Open in June 2011.
"As a result of a series of referrals to the Darts Regulation Authority relating to the behaviour of James Wade at PDC Tour Events, James Wade was found to be in breach of rule 4.1 of the DRA Rules," read a DRA statement.
"'No Player or Member shall act in a manner which may reasonably be considered to injure or discredit the DRA or bring the game of darts into disrepute'.
"He has been suspended from the next four tournaments.
"The DRA do not routinely publish the outcomes of hearings, but in this case it related to a senior player not being able to enter high-profile tournaments and it was important to clarify the reason for this."
Wade will be replaced as a Seeded Player for the Sydney Darts Masters by Paul Nicholson, with an additional qualifying place to be made available at the Oceanic Masters on Wednesday August 28.
