Chelsea are optimistic the injury suffered by star striker Alvaro Morata during their defeat by Manchester City is not too bad.
Spain want to take a look at the 24-year-old to make sure he will be fit for the international break.
He may miss one of their two World Cup qualifiers but should be back in contention for Chelsea against Crystal Palace in the Premier League in two weeks.
After the game, Chelsea manager Antonio Conte said he does not expect Morata to be out long term, saying it was a 'muscular problem'.
