Justin Herbert enters Week 5 of the 2026 NFL season with just four passing touchdowns through four games, alongside six interceptions and a 70.6 passer rating, as the Chargers sit at 0-4. The offense has struggled under new coordinator Mike McDaniel, with Herbert completing only 59.7 percent of passes amid 12 sacks and reduced efficiency. Key contributors to the passing attack face setbacks, including wide receiver Ladd McConkey’s foot injury and significant offensive line attrition—left tackle Rashawn Slater is sidelined 4-6 weeks with a high ankle sprain, right tackle Joe Alt is dealing with a neck issue, and additional guard and center depth concerns compound protection problems. Herbert remains healthy with no injury designation and is expected to start against Denver, but the combination of scheme adjustments, turnovers, and line instability has lowered season-long touchdown projections relative to his prior 20-26 touchdown averages.
