SAN DIEGO (AP) -- Philip Rivers says the commitment by the San Diego Chargers in giving him a four-year contract extension outweighs the uncertainty caused by the team's apparent desire to move to Los Angeles.

Rivers agreed Saturday night to the $84 million deal, which will allow him to retire as a Charger.

"Unless something changes from Tom's standpoint or upstairs, I'm going to be a Charger, wherever we are," Rivers said Monday.

General manager Tom Telesco called it "a very important day in the history of the Chargers," and noted that Rivers will be able to finish his career as a Charger, just like Hall of Famer Dan Fouts.

Team chairman Dean Spanos didn't attend the news conference. He and the rival Oakland Raiders have partnered on a proposed stadium in Carson.
