On August 15, 2015, the Chargers and Rivers agreed to a four-year, $84 million contract extension. Rivers started the 2015 season with 403 passing yards, two touchdowns, and two interceptions in the 33–28 victory over the Detroit Lions. On September 20, Rivers threw his 255th touchdown pass as a Charger, passing Dan Fouts as the franchise leader in touchdown passes. On October 18, in a game against the Green Bay Packers, Rivers set franchise records with 503 passing yards, 43 completions, and 65 attempts. In Week 12, against the Jacksonville Jaguars, he had 300 passing yards and season-high four passing touchdowns. The Chargers finished with a 4–12 record, last in the AFC West, their worst record since 2003. The Chargers went winless against divisional opponents for the first time since 1984. Despite the disappointing season, Rivers set career highs and franchise records with 437 pass completions on 661 pass attempts and 4,792 passing yards, which ranked second among NFL quarterbacks in 2015. He finished 11 yards short of breaking the franchise single-season passing yards record held by Fouts. Rivers was invited to the 2016 Pro Bowl as an alternate but declined the invitation, citing personal reasons. He was ranked 46th on the NFL Top 100 Players of 2016.
