As he recovers from surgery to repair a ruptured tendon in his knee, we have the chance to give back to the man who has given the game so much.
All it takes is a little wag of the finger. You know the one we're talking about. The swaggering index finger of R9. The simple goal celebration that defenders the world over know all too well.
This one undeniable show of triumph is the one way we're asking you to show your support.
Go to nikefutebol.com/ronaldo to see what they're doing in Brazil. Basically, here's the deal, when you score a goal throw up your finger in homage to the number one goal-scorer in World Cup history. If you can, get someone to video it and submit it to the R9 Tribute group. Nike Futebol will then upload it to their site, where it will play alongside other inspirational goals.
And for all the haters and doubters out there that say he can't come back, don't forget he's been in this position before and has made the critics eat their words each and every time.
