Luisao has pulled out of Brazil's squad to face England, after undergoing surgery.
The Benfica star has his appendix removed, and although not serious - it is enough to keep him from playing.
He had the operation on Wednesday - but that means he it not available to face England or Oman next week.
Indeed he remains a doubt for Benfica's next league match - which is the big derby with Sporting Lisbon.
Meanwhile, following Luisao withdrawal - coach Dunga has called up AC Milan stopper Thiago Silva.
