It was a rare and terrifying scene during tonight's Celtics-Sixers game as Boston swingman Mickael Pietrus was immobilized and wheeled off on a stretcher after a hard fall directly onto his spine in the second quarter. The incident was reminiscent of T.J. Ford's 2004 injury, as it's an uncommon sight to see a stretcher on a basketball court, period. We'll update the story as more information about Pietrus's status is made available. [ESPN]
