The Ivory Coast forward was substituted in the 37th minute of the 1-0 success at Stamford Bridge, with his replacement Joe Cole scoring the only goal. Drogba will miss Sunday's FIFA World Cup qualifier against Benin and possibly Chelsea's next UEFA Champions League match against PFC CSKA Moskva. "He has a muscular injury which could take two, three or four weeks' recovery," said Mourinho.
Drogba has scored in both of Chelsea's Group H victories so far but might not be back for the first of two matches against the Russian champions in London on 20 October. Chelsea did receive positive news today, however, with Adrian Mutu and Mateja Kezman expected to be fit for their next Premiership game at Manchester City FC on 16 October.
