Depending on how serious Durant's calf injury is, he could be fully healed in no time or a very long while.
A Grade I calf strain takes around 10 days to fully heal
A Grade II calf strain takes around 6 weeks.
A Grade III strain takes 3 months.
Absolute best case scenario the Warriors could hope for is a Grade I. But, it looks more like a Grade II.
Either way, K.D. won't be 100% come Game 6. So, he may likely have to sit out.
