Szczesny suffers dislocated finger

Arsenal goalkeeper Wojciech Szczesny suffered a dislocated finger in the Champions League defeat to Barcelona.

Szczesny was hurt saving Dani Alves' 16th-minute free-kick and left the pitch a couple of minutes later after receiving treatment.

Manuel Almunia replaced him and went on to make some eye-catching saves, but manager Arsene Wenger will hope his first-choice keeper will be able to play some part in the Barclays Premier League run-in.

The Gunners must wait for the results of medical tests before determining the likely duration of the young Pole's absence from first-team duty, as Wenger confirmed after the match.

"It's a dislocated finger," said the Frenchman. "We have to check the tendon to see how much treatment it will need. We don't know yet."

The injury is a particular concern for Wenger given that Szczesny's compatriot Lukasz Fabianski has been ruled out for the rest of the season following shoulder surgery - an injury that arose from saving Szczesny's shot in a pre-match warm-up.

In addition, Vito Mannone has been troubled by a thigh injury while on loan at Hull, which may leave Wenger to draw on inexperienced young professionals or enter the emergency loan market should Szczesny be sidelined for a lengthy period.
