Who's in, who's out for the Texans Week 3 preseason game at the Rams?

According to Bill O'Brien, every player that is available could see action on Saturday.

"Everybody that's healthy will play in the game," O'Brien said.

For players like J.J. Watt, DeAndre Hopkins, Jadeveon Clowney, Tyrann Mathieu, Will Fuller V, Benardrick McKinney, D.J. Reader and Johnathan Joseph, the upcoming game in Los Angeles will be the first game action they have seen since 2017.

Whitney Mercilus has not been practicing, but is expected to return for the start of the regular season.

Watt and Clowney are both full-go heading into Saturday's preseason game, while Mathieu could make his debut as a Texan. The starting safety says he is eager to suit up and get an interception.

"Oh yeah, it's going to be fun," Mathieu said. "It's going to be exciting. Obviously, going to L.A., playing against Todd Gurley and those guys. They have a great group of guys. The receivers are pretty good. The quarterback is getting better and better. Obviously, Todd, he speaks for himself. We'll have our hands full. Hopefully I get my feet wet Saturday."

Deshaun Watson played just one series in each of the two preseason games so far, while DeAndre Hopkins and Will Fuller V did not see a single snap. All three could be on the field together for the first time in 2018.

With just 19 days until the Texans' season opener, this entire week is different from previous weeks of training camp and most similar to what Week 1 would be like.

"We basically do a lot of things in our meetings that would, in some way, shape or form, simulate what we would do in a regular season week," O'Brien said. "Now, we're not into that type of schedule hours-wise. We're still in training camp mode when it comes to the amount of time we spend in meetings and practice and things like that, but in our meetings, we're starting to show them what a regular season Wednesday would look like, a regular season Thursday, a regular season Friday."

The Texans will travel to Los Angeles to face the Rams in their Week 3 preseason matchup. Kickoff is set for 3 p.m. CT Saturday on ABC-13 and SportsRadio 610.
