A recent professional darts match saw a rare disruption when a referee had to step in after a player mistakenly threw first in a leg, an error commentators stated they had "never seen before." The incident required the leg to be restarted, causing confusion and a halt to the game. This unusual event highlights the precise nature of darts regulations and the role of officials in maintaining fair play.

Unfolding of the Incident
The unusual occurrence happened during a match between William O'Connor and Mario Vandenbogaerde at the Players Championship 1 event in Hildesheim, Germany. After Vandenbogaerde had leveled the match at one leg each, he was scheduled to throw first in the subsequent leg. However, O'Connor stepped up to the oche and began his throw, apparently unaware of the correct order.
