Mayor Bob Filner says the Chargers will stay in San Diego for at least another year.
Filner said in his State of the City address Tuesday that the team will not opt out of its lease at Qualcomm Stadium in 2013.
The announcement, coming the same day the Chargers introduced new coach Mike McCoy, was expected despite falling revenues and thus-far failed efforts at building a new stadium.
The move is a blow to the NFL hopes of Los Angeles, which is looking to lure a team immediately.
Each year through 2020, the Chargers can announce intentions to leave if they pay off bonds sold to expand Qualcomm in 1997.
Chargers special counsel Mark Fabiani says the team will continue working with the city to find a permanent stadium solution.
