The Greek star missed back-to-back defeats to the Miami Heat due to a sore left knee and was unable to return against the Pacers.
Milwaukee face the Toronto Raptors on Thursday, but it remains to be seen if the 28-year-old forward – who participated in the warm-up before the Pacers game – will be back in action.
Bucks head coach Mike Budenholzer said of the two-time NBA MVP's injury: "We continue to think it's kind of the stuff that he and us have dealt with, for me it's each year that I've been here.
"We don't think it's anything more than that. Him being healthy, taking care of him is always our priority. We're probably always going to err on the side of caution. We know how important he is to us."
He added: "We'll see how he responds, see how he's feeling tomorrow,"
