Manchester United forward Cristiano Ronaldo is currently with the Portugal national team in Lisbon preparing for the World Cup in Qatar.
The 37 year old forward missed Portugal training today as he is currently suffering with a stomach bug, according to The Sun.
Portugal take on Nigeria in their capital city tomorrow in their final friendly before the tournament in the Middle East.
It remains to be seen whether Ronaldo will feature due to his illness.
Portugal begin their Group H campaign next Thursday against Ghana before then facing Uruguay and South Korea.
