The Los Angeles Chargers (4-7) take on the Denver Broncos (3-8) in Week 13 of the 2019 regular season.

Here are four matchups to keep an eye on that could ultimately determine the outcome of the game.

Chargers QB Philip Rivers vs. Broncos secondary

In the first meeting of the season, Rivers’ performance wasn’t all sunshine and rainbows as he was held to 211 passing yards, zero touchdowns and two interceptions. Since then, has accumulated 14 interceptions on the season and is looking to get back on track, but it won’t be easy facing a stout Broncos secondary.

Led by cornerback Chris Harris Jr. and safety Justin Simmons, Denver hasn’t made life easy on opposing quarterbacks, allowing only 207.5 passing yards per game, which ranks fifth in the NFL. Although they’re strong in this area, they haven’t been able to take the ball away, totaling only 10 takeaways this season.

Rivers, who’s been susceptible to making poor decisions and throwing the ball to whoever in hopes of them coming down with the catch, can’t do that on Sunday or else they will make him pay. Rivers has thrown six interceptions the past three games that the two teams have played against each other.
