ROCKER SAMBORA MAY DODGE DUI RAP

Richie Sambora may dodge a bullet in his DUI bust earlier this week, and not because of legal footwork — because he may not have been DUI.

Sambora volunteered to submit to a blood alcohol test after he was popped in Laguna Beach. It may take a week before we know the results. But several sources — who know what the alleged drunk drank — tell TMZ Richie simply didn't drink much at all before the cops stopped him, and the blood test may register below the .08 legal limit in Calif.
