Declan Donnelly says he accidentally struck Ant McPartlin’s step-daughter’s boyfriend on the head with a golf ball while on a golf course. According to the accounts shared by outlets, Donnelly describes the incident as unintentional and says the person he hit was in “a lot of pain,” adding that he feels “so bad” about what happened. The reports frame the event as a personal admission by Donnelly rather than a broader public incident report, with no additional details provided about medical treatment, the severity of injuries, or the circumstances of the play beyond the fact that a golf ball made contact with the man’s head. Both sources agree on the core elements: Donnelly’s disclosure, the accidental nature of the blow, the location being a golf course, the target being connected to Ant McPartlin through his step-daughter, and Donnelly’s expressed regret over the impact. No further corroborating information is included in the provided source summaries.
