Running back Austin Ekeler scored on what appeared to be the go-head score for the Chargers on a 16-yard reception with 39 seconds left in the game. However, Ekeler was ruled down at the 1-yard line.
Gordon was initially ruled down before the goal line, but a replay changed the call on the field.
Before that turnover, Gordon had 20 rushes from the 1-yard line for 11 touchdowns from 2015 to 2018, and he had not lost a fumble since Week 5 of the 2016 season, per ESPN Stats & Information.
The Chargers (2-5) have turned the ball over five times in goal-to-go situations this season, including Gordon's game-ending fumble, per ESPN Stats & Info. That's already tied for the most goal-to-go turnovers by a team in the past 15 seasons.
Although they scored in the first half for the first time in three games, the Chargers once again struggled to get into the end zone, finishing with 20 points. It's the fifth time this season that the Chargers have scored 20 points or fewer in a game. The Chargers are 0-5 in those games.
The Chargers, after losing their third straight game, are three games behind the AFC West-leading Kansas City Chiefs (5-2).
Buying Bosa's performance: Maybe Joey Bosa was tired of all the attention younger brother Nick Bosa of the San Francisco 49ers has received of late. On Sunday, Joey reminded the league that he can still play. The Ohio State product had two sacks, a forced fumble, a batted pass and four combined tackles -- including a tackle for a loss. Bosa now has five sacks on the season, two more than younger brother Nick. Even more impressive, Joey has 33 combined tackles as a defensive end, helping the Chargers plug up a leaky run defense.
QB breakdown: Playing about three hours from his hometown of Decatur, Alabama, with his parents in attendance, Philip Rivers finished 24-of-38 for 329 passing yards and two touchdowns. Rivers on Sunday passed 2004 draft classmates Eli Manning and Ben Roethlisberger in career passing yards. He now has 56,770 career passing yards, good enough for sixth all time in NFL history.
