Soccer World Cup 2018 in Russia (File)
Coach Zlatko Dalic sent Kalinic home following the team's 2-0 victory over Nigeria in their opening match.
Dalic said he wanted to use Kalinic as a substitute in the second half but the AC Milan forward, who was already warming up, told him he was not able to play because of a back problem.
Dalic said Kalinic did the same in a World Cup warm-up against Brazil and during training and was then sent home.
Croatia lost 4-2 to France in the final.
