EAGAN, Minn. (AP) — The Minnesota Vikings have secured naming rights for their new headquarters, with local physician group and sports medicine provider Twin Cities Orthopedics.

The Vikings announced a 20-year agreement with the orthopedic care company Tuesday at the groundbreaking ceremony for the training facility and team offices they'll move into in 2018. Financial terms weren't disclosed.

The Vikings' campus will be called the Twin Cities Orthopedics Performance Center. An expandable 6,000-seat venue, one of five outdoor fields, will be named TCO Stadium.

NFL Commissioner Roger Goodell attended the event, endorsing the project as "good for the game." The Vikings headquarters will sit on a 40-acre site intended to anchor a 200-acre development with commercial, retail and residential buildings among others.
