The NY Yankees Boston Red Sox rivalry may have just taken an interesting turn. Seems somewhere buried in the concrete of the new stadium is a Red Sox t-shirt.

A devilish Boston fan working on a concrete crew at the $1.3 billion stadium covertly buried a Red Sox T-shirt under what will become the visiting team's locker room to jinx the Yanks, two construction workers told The Post yesterday.

"In August, a Red Sox T-shirt was poured in a slab in the visitor's clubhouse. It's the curse of the Yankees," one worker said. "Nobody knows about it. It's in the floors, it's buried."
