Unrestricted free agent Andrei Kirilenkno is said to be in "excellent form and health" while playing for CSKA in Moscow after coming off pretty serious knee and back issues last season in the NBA. There's no guarantee that Kirilenko will return to the NBA once the lockout ends, but it is very likely. His health will remain an ongoing concern for the rest of his career, but as of now, it sounds like he's in great shape.
