The AFC South side face the unbeaten Seahawks at the Reliant Stadium tomorrow.
The head coach told reporters: "Well, we're going to have to play very physical to beat this football team. That's the way they play. They play fast, play physical.
"We pride ourselves on doing the same thing. We understand that and we worked really hard this week. I think we've pushed ourselves really good, pushed ourselves through today good.
"We understand the effort or the quality of play we're going to have to be successful I can tell you that."
The Texans were beaten 30-9 by the Baltimore Ravens last week.
