Glen Durrant will not attempt to earn a PDC Tour card and is to remain with the British Darts Organisation, the BDO have confirmed.
Durrant, 45, is the BDO's world number one and was the top seed at this year's World Championship at Lakeside.
However, the Middlesbrough thrower lost 5-4 to Scott Waites in the quarter-finals on Friday.
Durrant told BBC Tees in December that he would make a decision on his future after the tournament.
He won six ranking titles in 2015, including the prestigious World Masters and Finder Masters events.
A statement on the BDO website read: "Sue Williams, head of the British Darts Organisation, has announced that after speaking to Glen, he will be staying with the BDO and will not be attending (the PDC's) Q School later this month."
Q School takes place in Wigan on 13-16 January, with 16 players earning automatic Tour cards to play full-time on the Professional Darts Corporation circuit.
Further places will be available based on finishing positions in the final Q School Order of Merit.
