Herbert started Sunday's game against the Chiefs, Tom Krasovic of The San Diego Union-Tribune reports.
This surprising development is the result of Tyrod Taylor being listed as questionable by the Chargers with a chest injury. It remains to be seen if Taylor is able to enter the game at any point, but Herbert -- the No. 6 overall pick in the 2020 NFL Draft -- will have a chance to helm his team's offense in the meantime.
