Al Horford is officially questionable for Friday's game against the Toronto Raptors. Horford has been in quarantine since testing positive for COVID earlier this month and missed the Celtics season opener in their loss to the New York Knicks.
Horford also missed the Celtics final two games of the preseason against the Orlando Magic and Miami Heat in the league's health and safety protocols. Horford joined Jaylen Brown as the Celtics' two players to contract the virus during training camp, with the latter coming out of quarantine and straight into a career-high 46 point night against the Knicks.
