NFL owners unanimously approved a final tenant-lease contract between the San Diego Chargers and Los Angeles Rams on Wednesday.

The contract was agreed to in principle in January, when Rams owner Stan Kroenke received approval to move his team to Los Angeles. Owners also unanimously approved the Chargers using a debt waiver to finance a portion of the $650 million relocation fee.

Dean Spanos reiterated that he will not make a decision on whether his Chargers will remain in San Diego or move to Los Angeles until after the season is completed.

The Chargers have until Jan. 15 to exercise the team's option to move to Los Angeles.

"They've been working for 15 years [to keep the team] in their community," Roger Goodell said. "They're a big part of that community. They believe in that community, and they want to be a part of it.

"It's Dean's option by Jan. 15 to make a determination of whether he thinks he can make it work in San Diego or whether he decides to take the option to Los Angeles."
