Dick’s Sporting Goods Inc. is cutting short its long-term agreement with GSI Commerce Inc. to operate the retailer’s e-commerce site, according to a Dick’s Sporting Goods U.S. Securities and Exchange Commission document filed this week.

The filing does not say why the agreement’s expiration date is being cut from 2024 to 2017, and Dick’s Sporting Goods did not respond to an Internet Retailer request for comment.

Dick’s Sporting Goods, No. 101 in the Internet Retailer Top 500 guide, and GSI Commerce have worked together since 2001 when they signed a 10-year agreement; the two companies in 2008 extended that deal to 2024. The partnership predates eBay Inc.’s 2011 acquisition of GSI Commerce.

Since the eBay acquisition, Dick’s Sporting Goods has worked with GSI Commerce “to strengthen its relationship to more effectively leverage the company’s and GSI’s capabilities,” Dick’s Sporting Goods says in the filing.

GSI Commerce would not comment beyond the information contained in the Dick’s Sporting Goods filing.
