The Gunners youngster was taken to hospital where the shoulder was put back into place.

A decision will be taken on Wednesday morning over when Walcott will return to England.

Arsenal have been kept fully informed about the 19-year-old's treatment, with England boss Fabio Capello naturally disappointed.

"Our priority is Theo and making him as comfortable as possible before he returns to England,'' he said.

"We are all very disappointed but the important thing is for Theo to travel home and make a quick recovery.''
