Los Angeles Chargers quarterback Justin Herbert's availability for Week 4 is uncertain, leading to potential starting duties for veteran Taylor Heinicke. Heinicke, a former starter for the Washington Commanders, has been with the Chargers for a short period but is prepared to step in.

Despite recent challenges, Heinicke has focused on mastering the playbook rapidly. Chargers head coach Jim Harbaugh has opted for Heinicke over Easton Stick, citing Stick's struggles in preseason. The decision will hinge on Herbert's condition before the game against the Kansas City Chiefs.
