Cristiano Ronaldo has been able to take part in training with Portugal ahead of their World Cup match against the USA this weekend.

There had been concerns that the Real Madrid forward would have to miss the remainder of the tournament in Brazil after struggling with tendinitis in his knee.

However, USA Today reports that the current world player of the year managed to take part in light workouts with the rest of the squad earlier today, and appeared relaxed at the team's base in Campinas ahead of the trip to Manaus.

Teammate Beto insisted that Ronaldo will be fine to play on Sunday, describing the captain as "100% fit to play".
