The Hungarian Under-21 international was travelling back from his country’s 2-0 win against Italy with his parents.
Tamas Kadar's agent Viktor Kovesdi told the Chronicle: “Tamas played the full game against Italy at left-back.
“He played a very good game and Hungary won 2-0.
“Tamas got the ball from the Italians with a series of tough challenges before both Hungarian goals.
“Unfortunately, after the game he suffered a car accident together with his family.
“His father drove the car back home and it came up against a horde of wild boars.
“Thankfully nobody suffered an injury, but the car was completely damaged and two of the animals died.
“Tamas, his mum and dad did not suffer any injury.
“Tamas was in the back, his father drove and his mum was also in the front.”
