Portugal football star Cristiano Ronaldo is showing no signs of any trouble with his left knee and is jumping and shooting as usual, team-mate Miguel Veloso says.
Veloso says Ronaldo is training, jumping and shooting.
Ronaldo, who was suffering from tendinosis in his left knee before the World Cup, ended a training session early on Thursday and was photographed walking off the field with an ice pack on his left knee.
However, Portuguese media say it was just a precaution.
Portugal, thrashed 4-0 by Germany in their opening match on Tuesday, must beat the United States in Manaus on Monday to have any realistic chance of staying in the competition.
