Larry Sanders missed his fifth consecutive game Friday night and is out "due to personal reasons," according to Jason Kidd.
Sanders has not played since the Bucks' home loss to Charlotte on Dec. 23 and has been listed as out due to illness.
Zaza Pachulia will continue to start at center and John Henson is playing significant backup minutes. Kidd said there is no timetable for Sanders' return.
"That's a good question so you don't have to ask me tomorrow or Sunday or Monday, so there's no timetable," he said.
Kidd said Sanders is not taking part in any team activities.
"Being sick, away from the team, guys go on as you see," Kidd said. "Charlotte, we played without him. The other night we played without him (in Cleveland). It's nothing new to this ballclub. Injuries happen. The train keeps moving forward.
"It's just personal. There's nothing I can give you more. That's the way the question will be answered."
