Legendary announcer John McDonald and referee George Noble have been inducted into the PDC Hall of Fame.
Both men retired after the World Darts Championship final, which was their last match in professional darts.
PDC chief executive Matt Porter said: “John and George have played an instrumental role in the PDC’s growth over the last 20 years.
“John’s enthusiasm, passion and his ability to create an atmosphere through his delivery has been one of the main reasons why darts has become so loved.
“Someone has to set the scene and I think John’s voice has done that so well for us.
“When George came across to the PDC, there were quite a few players coming over from the BDO on a regular basis, and it was Tommy Cox, our tournament director, who persuaded him to join the PDC.
“At the time, it was that big it felt like signing a player. George really added to our roster of referees and he’s been a brilliant signing for us.”
