Philip Rivers fired three touchdown passes Sunday and the San Diego Chargers broke a four-game losing streak with a 34-24 victory over Pittsburgh. Rivers connected on 21-of-41 passes for 200 yards, with seven completions going to Danario Alexander for 88 yards and a pair of scores. The Chargers notched their first-ever regular-season win over Pittsburgh despite the return of Steelers quarterback Ben Roethlisberger, who sat out the previous three games with a sprained right shoulder and a rib injury. Roethlisberger responded by going 22-of-42 through the air for 285 yards, three scores and an interception for the Steelers (7-6). Mike Wallace led Pittsburgh\'s receivers with seven catches for 112 yards and two touchdowns.
