According to the Guardian, the Real Madrid superstar spent the session being assessed by the medical staff after injuring his left foot.
However, it is not known whether the injury will sideline him for the first-leg on Friday.
Ronaldo is seen as Portugal’s main attacking threat against the Zlatan Ibrahimovic led Sweden as the two countries battle it out for one of the final places at next year’s World Cup.
Ronaldo entered camp in stunning goal-scoring form, leading the scoring charts in both La Liga and the Champions League.
The 28-year-old only recently scored a hat-trick in Real Madrid’s 5-1 demolition of Real Sociedad to further underline his importance to Portugal manager Paulo Bento.
