Lisbon:Cristiano Ronaldo has returned from Real Madrid's pre-season tour of North America with the flu and has been ruled out of Portugal's midweek friendly against Liechtenstein, the Portuguese football federation confirmed on Monday.
The 24-year-old will be replaced by Lazio striker Eliseu for the tie in Vaduz on Wednesday. Eliseu was not named in coach Carlos Queiroz's 18-man squad but won the Italian Super Cup title with Lazio in Beijing on Saturday.
The game is the last chance for Queiroz to fine tune his team for upcoming qualifiers against Denmark and Hungary on September 5 and 9.
After six of 10 qualifiers Portugal sit third in Group 1, seven points behind leaders Denmark.
