SAN DIEGO (AP) - With a quarter of the season still to play, everything is pointing toward the free-falling San Diego Chargers having their first losing record in Norv Turner's six years as head coach.

All but mathematically eliminated from the playoffs for the third straight season, odds are pretty good the Chargers (4-8) will clinch a losing record Sunday. They play at Pittsburgh, where they're 0-14 in regular-season games, and the Steelers (7-5) have beaten both the Baltimore Ravens and Cincinnati Bengals.

The Chargers are coming off home losses to the Ravens and Bengals in which they blew fourth-quarter leads. They can't run the ball and Philip Rivers had two more crucial turnovers in Sunday's 20-13 loss to the Bengals.
