This is a very serious matter. Ainge can't say much because employers aren't allowed to share private medical information on employees. Doc speculates after the jump that Green won't be ready for the beginning of the season. We won't know for sure until tomorrow, but right now we could be looking at Jeff Green returning in a couple weeks or on the other hand possibly even having to retire due to this serious medical issue (most likely a heart issue). Right now we can only hope and pray it's the former.
