Goal.com reported Monday that they weren't sure if the team would "shrug" off his injury or if they will let Ronaldo play less due to his knee injury this summer.

Ronaldo didn't have a comment on his health status on social media, but did tweet Tuesday, "Great start of the season for Real Madrid with a win last night. Hala Madrid!"

Last week, Ronaldo scared his fans when he left a soccer game halfway through because of his injury. Real Madrid manager Carlo Ancelotti confirmed that Ronaldo would be going for tests after he was seen clutching his back during that game. "Cristiano had strain and was not comfortable. Tests tomorrow. At first it does not seem so serious," he told The Daily Mail.

"Cristiano always wants to play and it's that competitive streak that makes him the player he is, but he knows he will need to rest more to avoid a constant recurrence of this problem," a source close to Madrid told Goal.com earlier this summer after the World Cup. "The club are delighted to see him training at full pace as he has in previous years, but there is still some concern over how he will respond over the whole season."
