Sergio Aguero could be facing a potential ban for the Manchester derby after an apparent elbow on Winston Reid during his side's 3-1 victory over West Ham.
Manchester City striker Aguero and Reid were involved in a flashpoint during Sunday's clash at Etihad Stadium, when the pair tangled while challenging for a long ball in the 76th minute.
Referee Andre Marriner appeared not to see the incident but after Reid hit the deck, television replays showed Aguero flailing an arm that made contact with the New Zealander's throat.
"Hopefully nothing happens," he said. "If it happens, we accept and adapt.
"If we lose him, we lose him. We are going to play with 11."
The Croat said he was "angry" at his side's first-half display, which saw them two down inside 19 minutes to goals from Raheem Sterling and Fernandinho.
But when Sterling added his second injury time to cap a fine individual display, it was no more than City deserved.
"Man City were much better in the first half. They started better, were quicker, more aggressive and were better on the second balls," said Bilic.
"We gave them far too much time and space on the ball and they scored two goals.
"To be fair, at half-time I was angry about our mentality and character. We showed our quality and you need to show keeping the ball and wanting to hurt them.
"We played well in the second half but the team showed character, spirit and something up front. We have an awful lot of players missing.
"I expect a few players back after the [international] break – Lanzini, Payet, Feghouli and hopefully Carroll won't be long too."
