Dalic spoke to the press on Monday and revealed the AC Milan forward alleged he had a problem with his back during his warm-up, but this wasn't the first such occurrence of late, per Football Italia:
"During the Nigeria match, Kalinic was warming-up and should have come in the second half.
"However, he said he wasn't ready to go on because he felt a back problem. He did the same thing against Brazil and England, saying he wasn't ready, and for yesterday's training session too.
"I accepted it calmly, because I need ready and healthy players who can help their teammates. He's not like that, on three occasions he hasn't been ready, so I made this decision."
Milanese journalist Tancredi Palmeri was critical of the Croat, whom the Rossoneri signed on loan from Fiorentina last summer with an obligation to purchase him outright this year:
The 30-year-old had an unremarkable season at the San Siro, scoring only six times in 41 appearances—his lowest tally for a campaign since he moved to Italy and his worst since he was at Blackburn Rovers in 2010-11.
Kalinic has 15 goals in 42 international games, but his involvement has fallen in kind with his form at club level.
Milan fan account Amro illustrated the frustration of a Rossoneri supporter who might have thought a good World Cup turn-out would boost the club's chances of getting a good sale out of the player:
The news is particularly disappointing as Croatia are lacking in other No. 9 presences bar Mario Mandzukic, the player whom Kalinic was set to replace against Nigeria.
Saturday's clash against the Super Eagles marked Kalinic's fourth successive game starting on the bench under Dalic, who went with Mandzukic and Andrej Kramaric in attack, with Ivan Perisic and Ante Rebic flanking them.
Oghenekaro Etebo scored an own-goal before Luka Modric converted a penalty later on, propelling the Croats to the top of the group.
Croatia face Argentina in Nizhny Novgorod on Thursday, and it looks as though Dalic will prepare for the fixture with the disadvantage of being able to call upon only 22 players.
