Neither the St. Louis Rams nor the San Diego Chargers are in the NFL playoffs, but that hasn't prevented the Chargers from working on a defense to stop the Rams' latest offensive move.

Cover32.com, citing a tweet from Bleacher Report's Jason Cole, is reporting that the Chargers and owner Dean Spanos intend to block the Rams' potential move back to Los Angeles.

Quarterback Sam Bradford says taking a pay cut to remain with the St. Louis Rams won't be up to him

Cole issued a tweet Monday, saying, "Was told Monday that #Chargers owner Dean Spanos will try to block the #Rams from going to LA and believes he has 9 votes. We shall see."

The NFL requires that 75 percent of the owners must approve a team's bid for relocation, so the Chargers would need nine of the 32 NFL owners' votes to block the Rams' move.

Of course, all the maneuvering in Southern California at this point is premature.

St. Louis Rams owner Stan Kroenke is part of a group that announced plans on Monday to develop and 80,000-seat stadium and 6,000-seat arena near the former Hollywood Park racetrack in Inglewood, Calif., sandiego6.com reported.

The Rams are trying to get the city of St. Louis to build a new stadium to replace the aging Edward Jones Dome. Under the Rams' existing contract, the Los Angeles Times reported, they can end their 30-year lease a decade early because they have not agreed with the city on improvements for their current stadium.

The sides remain about $575 million apart on the money for those improvements. St. Louis city officials are expected to present another proposal to the team at the end of the month.

In October, Spanos told Sports Business Daily that roughly 25-30 percent of the franchise's business comes from Los Angeles and Orange counties, sandiego6.com reported.

"Putting a team in there right now, or two teams, would have a huge impact on our business going forward," Spanos told the publication. "So we are trying to protect our business in San Diego. ... It would really be harmful to us."

The San Diego Union-Tribune added that the Chargers also would be interested in moving to L.A. if they cannot find a replacement for Qualcomm Stadium.
