West Ham manager Avram Grant could miss the trip to Stoke on September 18.
The Hammers’ trip to the Britannia Stadium clashes with the Day of Atonement – an important date in the Jewish calendar.
And co-owner David Gold has revealed he will allow Grant to miss the game if the Israeli wishes to observe Yom Kippur.
Gold said: “It is difficult to stand in the way of religious conviction. Religion is a very personal thing and, much as I would like Avram at every game, I would respect his decision.
“It’s like a player who wants to miss a game to be at the birth of his child – no matter how much his team-mates might need him on the pitch, it’s hard to stand in his way of something which is so important in his personal life.
“It varies, from individual to individual, how important religion is to you and it’s a question of degrees. If my grandparents were still alive, they would not have gone to a match on Yom Kippur.
“Personally, I believe it is possible to fulfil both your religious obligations and you work obligations, but it’s not so easy to do both if you are absolutely devout.
“I don’t know Avram well enough yet to say whether he must be at the game, but you can’t make a judgement like this on behalf of someone else.”
