Chargers face a Week 4 setback as a makeshift line absorbed heavy pressure on Justin Herbert, despite limited sacks. With Rashawn Slater out and Mekhi Becton inactive, LA leaned on Joe Alt, Zion Johnson, Bradley Bozeman, Jamaree Salyer and Trey Pipkins III, but Alt left early, forcing Austin Deculus in. The looming test vs Washington’s front adds urgency for line reinforcements and keeps Herbert’s volume watchful for fantasy managers.
