Celtics coach Doc Rivers said Saturday that forward Kevin Garnett could miss another 10 days with a hyperextended right knee.

Garnett was kicked in his surgically repaired knee twice during a three-game trip this past week.

"KG's still 10 days, maybe, I don't know," said Rivers before Boston's win over Toronto.

"I have no idea, I honestly don't. There is some history with hyperextended knees that we kind of know that it takes at least two weeks, sometimes three. We know it won't be longer than that, but we don't know how quickly. There's a history there -- not with [Garnett] -- but with league history."

Rivers added that he doesn't see Garnett's injury as a long-term issue.

"It won't be that long," he said Friday. "When I did this, I looked at the schedule and the days off, and I thought this was the time to do it."
