Birmingham midfielder Alex McLeish has revealed midfielder Barry Ferguson played with a broken rib for an hour of the Carling Cup final triumph over Arsenal at Wembley.
Ferguson suffered the setback in a first-half challenge from Gunners midfielder Samir Nasri but the former Scotland international stayed on the pitch to help City gain a shock 2-1 win.
McLeish confirmed: "Barry Ferguson played an hour with a broken rib at Wembley. It shows that his pain threshold is frightening and also the character of the guy to do that. We all know how painful a broken rib can be."
He added: "I think it happened in a challenge with Nasri. He has taken a right bash in the ribs. It has been confirmed that there is a stress fracture and he is a doubt for the weekend."
Ferguson may have a pain-killing injection after the weekend if he is unfit to face West Brom at the weekend.
McLeish said: "Ferguson has had this before in our time at Rangers and he took an injection into the ribs.
"It was administered with a big giant needle - not something I would fancy - which alleviates the pain.
"If he doesn't make it for the weekend, that could be administered in the next week or two."
McLeish also confirmed fellow midfielder Craig Gardner is a doubt to face West Brom.
He suffered a thigh problem at Wembley and had to be substituted early in the second half.
