Not too surprising, I guess. Management realizes his importance and doesn't want to rush him back. Isn't he supposed to rejoin the team to start training next week, or something like that?
It'll take him awhile after that to get match fit, and Juve will have played at least the first 2-3 CL group stage matches by the time he's ready for CL football again. Take it slow, get him matches in Serie A and the Coppa, first. Have him ready to go for the knockouts, and beyond.
Looking forward to the club updating his status.
