Cavaliers guard Kyrie Irving won't make the trip to Philadelphia for Monday night's game because of lower back tightness.
Irving left Sunday's 109-90 loss to Dallas in the third quarter and didn't return. The All-Star point guard scored a season-low six points, making 2 of 9 shots in 25 minutes.
Irving, who will remain in Cleveland to get treatment, said he hurt the back in Friday's game at Charlotte.
