According to the Boston Globe, it is Rajon Rondo’s decision as to when to return to full practice and he has apparently been medically cleared. Coach Brad Stevens told reporters Monday that Rondo did “some practice” with the Celtics.
Rondo has been recovering from a torn ACL and while there have been no apparent setbacks, he’s right at the limits of his original timetable. Of course, every player is different and you don’t rush this sort of thing, particularly when you’re the Celtics and you’re not exactly in contention for anything.
Speaking in early October, Rondo said he was eager to return and would as soon as he got the go-ahead.
