Meanwhile, Alex Caruso will miss at least six to eight weeks following his wrist fracture, while Lonzo Ball is expected to miss four to six weeks following surgery to repair his meniscus.Without Ball, Chicago would not only lack a prolific defender but also a playmaker and shooter. The threat created by Lonzo from beyond the arc is essential to Chicago's attack.
