Fabio Capello has already stated that if Barry is likely to be fit for the opening Group C game against the United States in Rustenburg, he will be part of his 23-man party that is announced on June 1.
However, if recovery from an injury during City's home defeat by Tottenham on May 5 is not certain, Capello has a tricky decision to make.
The Italian has previously stated he will not select anyone who would not be capable of facing the United States.

England's players are due to return to their Austrian training camp in Irdning tomorrow for further training before playing a final warm-up match, against Japan, in Graz, on Sunday.
