Cristiano Ronaldo once again sat out a World Cup warm-up match as his side earned a late win against Mexico.
The reigning Ballon D’or winner and Portugal captain, 29, is suffering with tendinosis in his knee and also missed the draw with Greece.
A 93rd-minute header from a Bruno Alves header gave Portugal a win over their fellow World Cup finalists.
Portugal coach Paulo Bento said he “does not know” if Ronaldo will be fit for their World Cup opener on June 16. The Portuguese are paired with Ghana, Germany and the USA and they begin their campaign in Brazil against Germany, before matches against Group G rivals USA and Ghana respectively.
Ronaldo’s final chance to prove his fitness before the tournament could come in a warm-up game against the Republic of Ireland on Wednesday, June 11.
