Chelsea left back Wayne Bridge will miss the rest of the season with a double fracture of his ankle.
Bridge was taken to hospital after being carried off on a stretcher following a challenge by Newcastle United captain Alan Shearer just after halftime in Sunday's FA Cup fifth-round tie.
The 24-year-old had an operation on the fracture on Monday and will spend the rest of the season on the sidelines.
Chelsea, who sold their only other left back Celestine Babayaro to Newcastle in December, visit Barcelona on Wednesday in the first leg of the first Champions League knockout round.
They were already missing injured central defender Robert Huth and could also be without forward Damien Duff and defender William Gallas after they limped off at the end of Sunday's 1-0 defeat by Newcastle.
