Rome - AC Milan Brazilian star Kaka has said he is not worried about the inflammation that at the weekend sidelined him for the big match with Juventus, the ANSA news agency reported Monday.

"It's nothing serious. This morning's tests were negative and only showed an inflammation at the pelvic region," Kaka said. "I hope to recover as soon as possible, otherwise I'll be back in 2009.

"It may be enough (to rest) until tomorrow or it may take two or three months."

The 2007 Ballon d'Or winner was a crucial absentee for Milan as they lost 4-2 away to Juve on Sunday, slipping nine points below Serie A front-runners Inter Milan. (dpa)
