The Browns then traveled further west to take on the Chargers.  In the first quarter, the Chargers would score 2 field goals to start out:  Travis Coons kicked them both from 21 and 40 yards out to make the lead 3-0 to 6-0.  The Browns took the lead however when DeShone Kizer found David Njoku on a 28-yard pass to make it 7-6.  Though, the Chargers would move back into the lead when Coons kicked his third field goal of the day from 22 yards out to make it 9-7.  This would remain the halftime score as neither team scored in the second quarter.  In the third quarter however, the Chargers managed to increase their lead when Philip Rivers found Keenan Allen on a 7-yard pass to make it 16-7.  This would be followed up by Coons kicking a fourth field goal from 27 yards out to put his team up 19-7.  The Browns scored their only points in the half during the fourth quarter when Zane Gonzalez kicked a 35-yard field goal. The losing streak continued as the Browns fell to the Chargers 19-10.  With the loss, the Browns fell to 0-12 and the losing streak was extended to 13 consecutive games while their road losing streak was extended to 19 consecutive games.  The loss made the Browns 1-27 in the first 28 games under Jackson and Brown, overtaking the 1976-1977 Buccaneers (2-26) for the worst 28 game start under a HC and GM in NFL history. On the following Thursday, Brown was relieved of his GM duties.
