Horford is set to start his second stint in Boston after being traded for Kemba Walker in June. He played for the Celtics from 2016-19 and earned one of his five career All-Star berths in 2017-18.
The Celtics begin their regular season on Wednesday, Oct. 20, with a visit to Madison Square Garden to face Walker and the New York Knicks. Both Brown and Horford should have time to complete their quarantines and produce multiple negative tests in order to be cleared to play in the season opener.
Horford has played in two preseason games thus far. He made 28 appearances for the Oklahoma City Thunder in 2020-21 before being shut down for the season despite being completely healthy.
