Butler was injured late in Wednesday night's loss to Miami and did not return.
Butler was one of five players who missed Friday's game at the Pacers. Swingman Carlos Delfino (right foot), forward Ersan Ilyasova (right ankle), guard Brandon Knight (right hamstring) and center Larry Sanders (right thumb) all sat out for the short-handed Bucks. Guard Gary Neal (left foot) and center Zaza Pachulia (right foot) were game-time decisions.
Indiana was without swingman Danny Granger (strained left calf) as it tried to remain the NBA's last unbeaten team.
