One week after Boston Celtics big man Al Horford suffered a concussion during an off-day practice, coach Brad Stevens said the 10th-year veteran has not progressed in the NBA’s concussion protocol and he is uncertain when Horford will return to basketball activities.
Horford, who signed a four-year, $113 million contract with the Celtics over the summer, has missed Boston’s past three games. The concussion was diagnosed Tuesday, after he experienced nausea while attempting to practice a day after absorbing an inadvertent blow to the head from a teammate.
