Chicago Bulls guard Lonzo Ball hasn't played since mid-January due to surgery on his left meniscus. And it doesn't sound like Ball's return is getting close either.

Speaking before Friday's game at Phoenix, Bulls coach Billy Donovan said "He has not responded" when asked about Ball's rehab. Donovan added that there have been no setbacks, but Ball hasn't been able to ramp up his activity.

With three weeks left in the regular season, time is running out for Ball to return. His original timetable was 6-8 weeks, and that has now passed. Chicago has 12 regular season games remaining.
