The Sixers shot just 34.6 percent and 26.8 percent from three-point range. They also missed 13 free throws.
The Bulls were without Derrick Rose, Jimmy Butler, Joakim Noah and Taj Gibson because of various injuries.
Chicago improved to 40-26 with the win, while the Sixers fell to 14-50.

Ish Smith led the Sixers in scoring with 23 points. He also had six assists.

Stat-egic
