Horford will not play in Sunday's game against the Wizards for rest purposes.
The Celtics do not play again until Thursday, so Horford will end up getting some extended time off. The veteran big man is averaging 9.2 points, 5.3 rebounds, 2.3 assists, 2.2 triples, 0.9 blocks and 0.7 steals across 28.0 minutes in 19 games this season. In his absence, Neemias Queta and Luke Kornet could see more depth minutes at center.
