Simmons had been described as pain-free for the majority of the past month but began to cite soreness in his back on Friday, and a scheduled scrimmage was pushed back, multiple sources said. Simmons conducted two full-court scrimmages last week on Monday and Wednesday, in which there was low intensity displayed, those sources said. Throughout Simmons’ rehab, both Durant and Irving, for their part, publicly downplayed their expectations for a Simmons return and said the goal is to get him healthy.
