Birmingham have received a blow with news that Neal Eardley has been ruled out for the rest of the season.
The right-back limped off in the first half of Saturday's 1-1 home draw against Ipswich and scans have since revealed he has ruptured his medial ligament and has also suffered a partial tear to his anterior cruciate ligament.
Eardley, 24, who now requires surgery, was making only his seventh appearance for Blues since arriving over the summer from Blackpool on a three-year deal.
The setback makes manager Lee Clark's deadline-day signing of Paul Caddis from Swindon an even more important capture.
Caddis, who also operates at right-back, enjoyed a successful season-long loan at St Andrew's last term and was a key summer target for Clark, who had looked to have missed out due to financial constraints at the Midlands club before securing a late move for his services.
