Steel City invaded San Diego this past Monday night.
In fact, Chargers quarterback had to operate in away field conditions against the Pittsburgh Steelers.
"We were in silent count. There was no chance," Rivers told the San Diego Union Tribune. "We're checking in and out of plays. I'm usually hoarse after those road games. I'm going to be today as well. I don't know where to credit for that, whether you give it to Pittsburgh for just how many fans there are, whether they travel or whether they are just all over the place.
"Our fans that were here did their best. Obviously, we had the Steelers fans quieted for some time. It was loud on some third downs for our defense. (Crowd noise) did not affect the outcome. It's way down the list, but it was unique to say the least."
