The official announcement:
KD will be reevaluated in 4 weeks. Draymond indicated he'll be back in 6.

I heard on ESPN2 Dray texted Mark Spears and said (paraphrasing), "Was better than we thought it'd be. It sucks, but 6 weeks ain't bad." So it's likely 6 weeks is the actual timetable, and he could be back before the playoffs.
I'm not a religious man, but I'm praying for KD.
