Albion boss Steve Coppell has told Michel Kuipers to learn from his dismissal in Saturday's 3-2 victory over Bradford City.
Kuipers was sent off in the final minutes after bringing down Stephen Warnock in a rash challenge which allowed the Bantams to set up a nervy final few minutes at Withdean.
It was the second penalty the big Dutch keeper had conceded at Withdean in as many games.
Coppell said: "Goalkeepers live or die by those decisions.
"It's expensive for us. He is going to miss a game now and he has got to judge the pace of this division a little bit more and not make that commitment."
Kuipers is now suspended for the next home match against Derby on November 16.
Meanwhile, Paul Brooker is banned for the trip to Molineux on November 11 after he saw red against Crystal Palace.
