Theo Walcott ruled out of England's trip to Poland

LONDON (REUTERS) - England forward Theo Walcott has been ruled out of their World Cup qualifier in Poland on Tuesday with a chest injury, the FA said on Saturday.

Walcott was clattered by San Marino goalkeeper Aldo Simoncini five minutes into England's 5-0 Group H victory at Wembley on Friday and spent the night in a London hospital under observation.

"He was monitored overnight as a precaution and following scan results today will return to his club (Arsenal) for further treatment," a statement said.

England coach Roy Hodgson was critical of Simoncini's clumsy challenge which flattened Walcott, suggesting the keeper should have been sent off for the tackle.
