Portugal midfielder Paulo Sousa had to cut short his training session for the second consecutive day yesterday and is a doubt for his country's opening Euro 2000 fixture against England on June 12th.
Sousa, who plays for Italian club Parma, is suffering from a strained thigh and missed last Friday's 3-0 win over Wales.
Portuguese team doctor Joao Paulo Almeida said: "We do not know if he will be able to play against England."
