Bulls guard Lonzo Ball said at media day Monday that he’s about halfway through the rehab process after his cartilage-transplant surgery and that there’s no set timeline on when he’ll be back.
‘‘The surgery was a really big surgery,’’ Ball said. ‘‘We all came together with a plan moving forward, and it’s not really, I wouldn’t say, a set timeline. But I pretty much have this whole year to get as healthy as possible and [get] ready to go next season.
