West Ham boss Allardyce pleased with Petric debut
Allardyce admits a Capital One Cup appearance against Cardiff City is unlikely.
Allardyce said: "I am not so sure he will start. He played a highly competitive game in the Premier League in only week two of his pre-season. Normally he would be playing 45 minutes against Cardiff City.
"We have to be careful with him because we want to keep him fit, but he will be in the squad."
