Walcott ruled out for three months

"Theo dislocated his shoulder during training. He will be out for at least three months," Arsenal manager Arsene Wenger told TF1 television channel.

Walcott has earlier sustained a minor injury problem which kept him out of Arsenal's UEFA Champions League clash against Fenerbahce on November 5th.

The injury is a massive blow for the player, who already underwent a shoulder surgery, which kept him out for few months last season.

The injury is set to hinder Walcott's progress this season, after the 19-year-old earned a regular place in Fabio Capello's England set up, following some impressive displays for Arsenal since the start of the season.
