This is without a doubt a 1-2 week injury but you bet your ass he plays game 7 because cp3 is a competitor
i believe he's done for this series, but i don't believe for a second that he won't make it back for at least game 3 of the finals.
If we lose game 6, I think he plays game 7 even if banged up. Just too much at stake. He will be playing nowhere near 100% though.
