NASHVILLE, Tenn. (AP) — Philip Rivers and the Los Angeles Chargers thought they scored the go-ahead touchdown not once, but twice inside the final minute against the Tennessee Titans. Yet again, the Chargers found a way to stop themselves near the goal line in a 23-20 loss Sunday. After the replay official ruled Austin Ekeler had been stopped a yard outside the goal line off a pass from Rivers, the Chargers thought Melvin Gordon scored on a 1-yard run that was overturned again for being short of the goal line.
