BOSTON - Some might call it a curse, others might call it a cure for cancer.

The Boston Red Sox’s official charity, the Jimmy Fund, is auctioning off the David Ortiz jersey that was buried under the New York Yankees‘ new stadium by a Boston fan trying to curse its American League rivals.

The auction began Thursday on eBay and lasts one week. The starting bid is $500.

All proceeds will go to the children’s cancer charity, which is affiliated with Boston’s Dana-Farber Cancer Institute.

Construction worker Gino Castignoli had dropped the jersey in wet concrete, apparently hoping to hex the archrival Yankees.

Tipsters led the Yankees to the jersey’s location, and it was dug up Sunday.
