Midfielder Andres Iniesta is still doubtful for Spain's Group H game against Switzerland due to injury.
Iniesta missed Spain's first training session in South Africa after the team touched down on Thursday due to a thigh injury sustained in the 6-0 win over Poland last week.
Iniesta was substituted before the break in that match, and team officials claimed afterwards it was just a precautionary move. But the problem may be more serious than first thought given Iniesta's limited training session.
It's now understood Spain coach Vincente Del Bosque will give the midfielder a late fitness test ahead of the June 16 clash in Durban.
