The Hammers were beaten 2-1 by Slovenian side NK Domzale in the first leg of their third round Europa League qualifiers on Thursday, making next week's fixture at the Olympic Stadium a must-win if they want to make the play-off round.
Regarding the team Bilic will have available to him, Jurcevic has revealed that there is a cloud over summer loan signing Gokhan Tore and playmaker Manuel Lanzini but suggests that Angelo Ogbonna and James Collins will be back to strengthen central defence.
"It's difficult to say which players will play because Gokhan Tore was injured in training on Monday and he must have a scan," said Jurcevic.
"Tore has hurt his knee, but we are not sure how serious, It was a very easy training, but after five minutes he felt some pain in his knee. He will have a scan on Friday and we hope it will not be serious.
"With Lanzini, we don't have exact information. He will come back from America, where he wanted to play in the Olympic Games for Argentina. We don't know, but we think he will not be fit for the next game against Domzale."
