Chelsea left-back Ashley Cole is set to be sidelined for around two weeks with a hamstring injury suffered in Monday's FA Cup quarter-final win over Manchester United.
The England international sustained the damage in the first half of the Blues' 1-0 final eight triumph at Stamford Bridge and will now miss some key matches.
"This kind of injury, at least two weeks (out)," said manager Rafael Benitez.
Cole is out of Thursday's Europa League quarter-final first leg with Rubin Kazan, the weekend's Premier League meeting with Sunderland, the Rubin return leg next week and most likely the FA Cup semi-final with Manchester City on April 14.
