The father of Turkey forward Umut Bulut was killed in the bombing in Ankara, his club Galatasaray have said.
Kemal Bulut was one of at least 37 people who died on Sunday when a car bomb exploded in the Turkish capital.
"Our capital was shaken by the fatal attack which targeted innocent people and we've once again been devastated by the news we received," the club said.
"We have learned with sorrow that Umut Bulut's father Kemal Bulut was one of the people to lose their lives."
The 32-year-old international has made 36 appearances for his country and won the Süper Lig with the Istanbul-based club last season.
"The club and the players offer their condolences to Umut Bulut and his family," added a club statement. "The pain is very great."
