The Texans have Tuesday off, and when they return to work on Wednesday, their focus will be on the Chargers.

Both teams are 1-1 in 2019, and Los Angeles returns home after a Week 2 loss at Detroit. But they're still quarterbacked by 8-time Pro Bowler Philip Rivers, and that's more than enough of a challenge. Through two games, the 16-year pro has completed 65.7 percent of his passes for 626 yards, with three touchdowns and a pair of interceptions. He's been sacked five times. He and the Chargers beat the Texans the last time these two teams played, triumphing 21-13 in November of 2016.

Cornerback Johnathan Joseph has faced Rivers five times in his career: twice with Houston and three other times with the Bengals. He said the veteran signal-caller "has always been right up there at the top" with the League's elite quarterbacks.

"He can make all the throws," Joseph said. "They talked about his throwing motion years ago, when I was young, but he's consistently thrown for 4,000, 5,000 yards year in and year out. He's put up touchdown numbers, very little interception numbers. "He's a Hall of Fame type of guy."

Outside linebacker Whitney Mercilus, who's already rung up three sacks in 2019, described how Rivers' brain and quick-draw are two of his strengths.

"Smart quarterback," Mercilus said. "He gets the ball out pretty quickly as well. We've just got to go through the film (from yesterday) and watch it, and see what we did wrong."

Head coach Bill O'Brien pointed out how tough the Chargers will be for Houston.

"It's going to be a big challenge, we've got to get going on them today," O'Brien said. "We've got to kind of talk about yesterday, things that we need to improve on that could carry over to that game and then we need to turn the page and we need to get going on the Chargers."

Kickoff is set for 3:25 p.m. CT on Sunday at Dignity Healthy Sports Park.
