Chelsea's Boulahrouz injured

League champions Chelsea lost another defender yesterday when Khalid Boulahrouz dislocated his shoulder in the first half of the 4-0 FA Cup fifth-round win over Norwich City.

It was the Dutch international's first game since he injured his knee on Jan. 2.

Chelsea were eight weeks without inspirational captain John Terry, who returned to action a fortnight ago. The Londoners were also minus centre back Ricardo Carvalho last week due to a fever.

Manager Jose Mourinho was upbeat with two more cup games to come, against his former club Porto in the first knockout round of the Champions League on Wednesday and in the League Cup final against Arsenal in Cardiff next Sunday.

"Boulahrouz will be out for quite some time," Mourinho said. "That was the only thing not positive. After five consecutive victories, the confidence is back and I could rest some players."
