FORMER Town defender Efe Sodje will take no further part in Southend's bid for promotion from League I this season.
The 33-year-old centre-back fractured his ankle while falling awkwardly during Saturday's 1-1 draw at Bournemouth.
Physio John Stannard said: "We took Efe for a scan and it's not good news. We are looking at three months before he can return."
Spencer Prior had already been ruled out for the rest of the season after injuring knee ligaments.
With six games to go, leaders Southend have a six-point advantage over Brentford and Town, who are both on 68.
Meanwhile Middlesbrough have been rocked by the news that Spanish midfielder Gaizka Mendieta will miss the rest of the season after breaking a bone in his foot in training.
The 32-year-old, an unused substitute in Sunday's 1-0 Premiership win at Manchester City, suffered a fractured metatarsal - the same injury which has sidelined England striker Michael Owen since December.
The setback came three days ahead of the vital UEFA Cup quarter-final, second leg clash with Basle, who hold a 2-0 lead from their home leg.
Mendieta will need an operation to repair the damage and is expected to be out of action for 12 weeks.
