Kaka, who left Real Madrid this summer on a free transfer to join AC Milan, has suffered an injury during his first game after his return to the San Siro.
The Brazilian picked up an adductor injury in AC Milan’s 2-2 draw against Torino - his first competitive match after returning to the San Siro outfit, after a four-year spell in Real Madrid.
Kaka has announced in a video on the site of the club that he will suspend his wages until he is fully fit. Some reports say that he'll be out for 2-3 weeks, while others indicat a two-month lay-off is more likely.
In an interview with the club’s website, Kaka said: "Yesterday [Sunday] was a tough day for me as I found out about my injury.
"I certainly didn’t expect this type of injury at this time. It has been hard and difficult."
Kaka has also revealed that he will waive his right to wages until he fully recovers from his injury.
"I spoke to the club a lot yesterday [Sunday], to (vice-president Adriano) Galliani and to the doctors to decide on a few things," Kaka was quoted further.
"I have decided that I don’t want anything from Milan except their (moral) support and affection.
"Until I am fit again and ready to play, I have decided not to receive my wages."
The Ballon d'Or winner joins the likes of Ignazio Abate and Stephan El Shaarawy on the list of injured players who will miss Milan's Champions League game against Celtic.
