SAN DIEGO -- They’ve faced each other nine times since he’s been in the league as a head coach. And while the Chicago Bears head coach John Fox is 7-2 against teams led by San Diego Chargers quarterback Philip Rivers, he still has a healthy amount of respect for him.

“You’ve just got to mix it up,” Fox said. “You’re not going to stop him. You do your best to slow him down. He’s a tremendous competitor and we’ve been going at it for a while. I even go back to when I was in Carolina and he was playing his college ball (at North Carolina State) then. And you just run into people in different venues and whatnot.

“So we’ve kind of followed each other throughout the years, and I know what a tremendous competitor he is. He’s going to get his. He’s going to hurt you in some cases. And you just try and limit it as best you can.”

In nine contests against Fox-coached teams, Rivers has averaged just 225 passing yards a game, totaling 16 touchdowns and 11 interceptions.

Rivers has never thrown for 300 yards against a Fox-coached defense.

At the midpoint of the 2015 season, Rivers leads the league in completions (243), attempts (348) and passing yards (2,753). He’s currently on pace to break Peyton Manning’s single-season record of 5,504 passing yards, set in 2013.

Rivers has thrown for at least 300 passing yards in a team-record five straight games.
