The Chargers elevated Herbert from their practice squad to their active roster for Sunday's matchup in Seattle.
Herbert will get the opportunity to work his brother, QB Justin Herbert, for a second straight week. In Week 3 versus Buffalo, the tight-end Herbert logged just one offensive snap and six special-teams snaps without logging any stats. He'll likely have a minor role again this Sunday despite starter Charlie Kolar (forearm) having already been ruled out.
