Chargers coach Anthony Lynn revealed to reporters after the game that he did not learn Taylor was unavailable until after the coin toss. Taylor was taken to the hospital to be further evaluated. It's not clear what happened to him during warm-ups.
Herbert, the No. 6 overall pick in April's draft, went 22-of-33 for 311 yards, one touchdown and one interception in his debut. Unfortunately for L.A., Patrick Mahomes and the Chiefs rallied for a 23-20 overtime victory.
In his first season with the Chargers, Taylor came over to serve as the primary backup behind Philip Rivers. He spent the 2018 season with the Cleveland Browns before being replaced by Baker Mayfield.
Taylor passed for 208 yards and no touchdowns in a Week 1 victory over the Cincinnati Bengals while rushing six times for seven yards.
Herbert was the third quarterback selected in the draft behind Joe Burrow and Tua Tagovailoa. The former Ducks star passed for more than 10,000 yards in college with 95 total touchdowns and 23 interceptions over four years.
