Back pain forces withdrawal of Tiger Woods in Honda Classic
In worrying sign for lead up to Augusta Masters, Tiger leaves PGA National on 13th in final round

The road to the Masters got off to a bumpy start for Tiger Woods when he withdrew from the Honda Classic with what he said was a lower back injury.
Woods was five-over par for the final round when he shook hands with Luke Guthrie on the 13th green and told him he was finished. It was the farthest point at PGA National, and the tournament sent a van to collect Woods and his family.

Woods said through spokesman Glenn Greenspan it was a lower back problem that had started on Sunday morning as he was warming up. He was to defend his title this week in the Cadillac Championship.
