Portugal great Eusebio was hospitalized overnight in Poland after complaining of feeling ill.

The 70-year-old Eusebio felt sick late Saturday in Opalenica, where he was accompanying the Portuguese team during its European Championship campaign, the Portuguese Football Federation said.

Eusebio, a former Benfica star, was taken to a hospital in Poznan as a precautionary measure and for tests, the federation said. Eusebio was still undergoing treatment Sunday, Mikolaj Piotrowski, a spokesman for the Polish organizers of Euro 2012, said.

No further details were immediately available on why he was hospitalized. This is the fourth time since December that Eusebio, who scored 41 goals in 64 games for Portugal, has sought hospital treatment. The other three times were for pneumonia, blood pressure and severe neck pain.

Eusebio da Silva Ferreira, who was born in Mozambique when it was still a Portuguese colony, became a national icon after his stunning performances in the 1960s for Benfica and Portugal's national team.

In 1998, FIFA named him one of the 10 best football players of all time. He may be best known for his performances at the 1966 World Cup, where he scored four goals in the quarterfinals to help Portugal overcome a 3-0 deficit against North Korea to win 5-3.

The current Portugal side, which faces Spain in the Euro 2012 semifinals Wednesday, was closing following the former star's health.

''We are all with him, but we know he's a strong man,'' Portugal defender Jao Pereira said. ''He's always showed that during his sports career and afterwards, and we know he's going to recover quickly. So that's why we're not that worried because we're confident in his recovery.''
