The NBA has suspended Celtics forward one game after the big man refused to cut his hair. Apparently the league and the Celtics have been negotiating this hairy infraction for a few months now and the league gave Olynyk until the the end of March to at least get a trim. Olynyk had agreed to it, but then backed out when the Gonzaga Bulldogs marched to the Final 4. Olynyk says that the Bulldogs have always drawn strength from his hair and would feel any loss this weekend would be on his shoulders.
The reason for the NBA demanding a trim isn't 100% known, but opposing players have been complaining that Olynyk draws extra fouls when they accidentally touch his hair and it's too abundant to miss.
