Celtics' Al Horford: Out Monday following birth of child
Horford won't play Monday against the Heat for personal reasons.
Horford's wife recently gave birth to the couple's second child, so the center will remain away from the team Monday night. He's expected to be present for practice Tuesday, so Horford figures to return to the lineup Wednesday against the Pistons. In Horford's absence Monday, Kelly Olynyk is the favorite to enter the starting five at center, while Tyler Zeller figures to see enhanced playing time off the bench.
