Everton midfielder Mo Besic played in the 2-0 Premier League defeat at Chelsea despite his father being shot in a dispute in his native Bosnia, manager Ronald Koeman said.
Reports in Bosnia said Besic's father had been shot in the leg and hand and was in hospital.
Everton brought on Besic, 24, as a half-time substitute at Stamford Bridge and Koeman said after the game: "I spoke to Mo yesterday evening. He spoke to his father. I don't like to talk more in detail.
"Today after the game he told me he will be in contact with his family. I don't know really what happened, but what came out in the paper, that's true."
Koeman said Besic had told him he was "ready" to play if called upon and added: "After the game he will talk to the family, what he needs to do.
"It's always the decision by the player. It's a family question. He showed commitment. He spoke to his family about what happened yesterday.
"Maybe he'll get off to see his family and be part of his family for the next couple of days."
