Rivers completed 19-of-25 passes and had all of his scoring tosses in the first half for the Chargers (1-2), who got 67 rushing yards and a pair of touchdowns from LaDainian Tomlinson. Tomlinson, recovering from a jammed right big toe that forced him to miss most of last week's 39-38 loss at Denver, carried the ball 26 times.
San Diego's Antonio Cromartie had a pair of interceptions, returning one 52 yards for a touchdown, as the Chargers took advantage of three first-half turnovers.
Favre connected on 30-of-42 passes with two interceptions for the Jets (1-2).
David Barrett picked off a Rivers pass and returned it 25 yards for the game's first touchdown for the Jets, but New York stumbled, giving up 31 points in the first half, and trailing by 17 at halftime.
