The Pittsburgh Steelers managed to take down the Los Angeles Chargers, but part of that was due to their opponent’s quarterback situation. Justin Herbert is one of the NFL’s best quarterbacks, but an ankle injury kept him limited in practice this week. It wasn’t clear if he was going to start in Week 3, but he did, and for a little more than half the game, he looked good. However, after he took a sack in the third quarter, he seemed to reaggravate his injury, leaving the game. Head coach Jim Harbaugh explained the situation.
