After an off season of uncertainty, Philip Rivers will be staying as a San Diego Charger. 

ESPN reports that the San Diego Chargers and quarterback Rivers agree to a four-year, $83.25 million deal with $65 million in guarantee money. The $65 million guaranteed would give Rivers the most guaranteed money of any player under a current contract. 

Earlier this off season, rumors were swirling that Rivers was available via trade. The fourth overall pick in the 2004 NFL Draft threw for 4,286 yards with 31 touchdowns and 18 interceptions last season and led the team to a 9-7 record. In his career, Rivers led the Chargers to the postseason four times.

In 2006, Rivers signed a six-year $92 million extension to stay with the Chargers. This was his final year of that deal. He was scheduled to make $15.75 million this season. In March, Rivers said that he would be signing an extension as long as it didn't dragged into the season.

"My mentality has been the same since March, which is I'm playing this season right here," he said. "Like I said a few weeks ago, if something happens, it does. But I don't think you should hold your breath for an update any time soon." 

NFL reports that Rivers also has a no trade clause in his contract, meaning he cannot be traded to a team. 

The Chargers have been in the news announcing that they have partnered with the Oakland Raiders on plans of a $1.6 billion stadium in Carson, California. The Chargers and Raiders are eying a move to Los Angeles if their respective cities don't give them a new stadium. 

In his career, Rivers has thrown for 36,655 yards with 252 touchdowns and 122 interceptions. He has been to the Pro Bowl five times in his career.
