England forward Theo Walcott has been ruled out of their World Cup qualifier in Poland on Tuesday with a chest injury, the FA said.
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.
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.
"I think if I describe it as a reckless challenge I am being very kind," Hodgson told reporters after the win had put England three points clear at the top of the group with seven points.
"It was a very fierce challenge. I don't believe for one minute there was any malice when he went for the ball but it was a very bad challenge."
Walcott's absence will be a blow to England as they prepare for what will be a much tougher assignment in Warsaw.
