Graham Potter admitted Albion were made to pay for some poor decisions as they went down 2-1 to Wolves at Molineux.
Skipper Lewis Dunk, who had earlier put Albion ahead, and Neal Maupay were both sent off in the second half as Wolves won it with goals in the last 14 minutes from substitute Adama Traore and Morgan Gibbs-White.
“It’s a missed opportunity,” said Potter. “We played well in the first half and deserved our lead but then at the start of the second half we allowed Wolves to get into the game.
“We made some poor decisions and suffered for that in terms of a red card, and it left us with a long time to play with ten men.
“The boys defended quite well and gave everything but it was too much for us in the end. They had a lot of pressure but not too many chances, but then Traore came on and stretched the game for Wolves.”
Although Albion have a ten-point cushion above the bottom three their Premier League status for next season is still not secure, and both Dunk and Maupay will be suspended for next Saturday’s Amex clash against West Ham United.
“Until we are mathematically safe then we have to keep fighting for points and we have said that all along,” added Potter. “I was walking off at the end so I didn’t see what happened but if Neal has been sent off then it’s something he needs to learn from.”
