Boston Celtics big man Al Horford has tested positive for Covid-19 and will remain out of action for some time.

Horford is in quarantine and the Celtics will provide further updates in the coming days. The veteran power forward/center is the second Celtics to test positive for the virus, after Jaylen Brown.

It’s still unclear if Al Horford will be available for Boston’s opening game vs the New York Knicks at Madison Square Garden on October 20.
