Arsenal have lost Theo Walcott for the next two games.

The Daily Star says the England winger suffered a bruised lung and was coughing up blood after a collision with San Marino goalkeeper Aldo Simoncini at Wembley last Friday.

Walcott, 23, had trouble breathing as a result of the injury and did not feature in yesterday's World Cup qualifier against Poland.

He has been ruled out of Arsenal's Premier League trip to Norwich on Saturday, as well as next Wednesday's ­Champions League clash with Schalke.
