Tyrod Taylor had a lung punctured by a Los Angeles Chargers' team doctor while trying to administer a pain-killing injection in his cracked ribs, which led to Justin Herbert starting Week 2 unexpectedly. The injection that Taylor received is not entirely uncommon, but it carries a risk because a doctor injects without seeing where the needle is going.

Anthony Lynn strongly backed Taylor on Sunday night and again this week.

The Chargers previously said Taylor suffered complications from an injection.

The NFL Players Association is investigating the medical mishap.
