DETROIT (Reuters) - Campbell Soup Co said on Friday that it has renewed its sponsorship agreement with the National Football League for three years, maintaining its position as the U.S. sports league's official soup and chili.

Financial terms of the deal were not disclosed.

Campbell's Chunky soup has been an official sponsor of the NFL since 1997 and the NFL has been prominently featured in Chunky soup advertising for many years.

"We are excited to renew a sponsorship that has been effective for the Chunky brand for more than a decade," Campbell Vice President Michael Barkley said in a statement.

"We are confident that our relationship with the NFL will continue to help us position the Chunky brand as a hearty and nutritious meal-time option," he added. "The NFL will be an important component in our marketing plans next season."
