Per Rick Carlisle in his postgame comments, J.J. Barea will be out “weeks, not days” with a left calf strain. The new injury is to the same calf he injured before, but a different area.
Barea has had the injury bug badly this season. His injury in November this season appeared to be an Achilles injury when it happened, but somewhat fortunately was only a muscle tear. That injury was still significant enough to keep him out for about a month and a half. The past several games have seen Barea ramp up from a minutes restriction as he worked his way back into game shape from that injury.
