Theo Walcott ruled out of Man United clash after suffering injury setback

Theo Walcott has suffered another injury setback, ruling him out of Saturday's Premier League showdown against Manchester United.
The Arsenal forward has only just come back from fitness following a nine month lay-off with a serious knee injury.
But Walcott has now returned from England duty with a groin problem.
'Theo is not available for tomorrow's clash, he has a tight groin,' said Wenger.
