Officials from the San Diego Chargers believe they can build a new football stadium downtown to be ready by 2022.

The stadium would be municipally owned by a new Joint Powers Authority, which would be created to run the stadium and all non-football entertainment events, including concerts, the report said.

The proposed 65,000-seat downtown stadium would call for the Chargers to apply $650 million in private funding toward the new venue, which would include a $300 million contribution from the NFL.

The Chargers previously said the downtown venue would "create an unparalleled entertainment and sports district" to host Super Bowls and provide a home for Comic-Con.

If the ballot measure for a new stadium fails, the Chargers could join the Los Angeles Rams in a stadium in Inglewood scheduled to open in 2019.
