SHAQ TURNED AWAY AT NYC CLUB

Shaquille O'Neal couldn't power his way through the lane at a New York nightclub this weekend -- getting TURNED AWAY at the door ... all because he was dressed like a lumberjack.

TMZ has learned ... Shaq rolled up to nightclub/restaurant Mars 2112 on Saturday night wearing jeans, a sweatshirt, tennis shoes and a beanie (pictured above with random fan later that night).
