Houston faltered in the fourth quarter for the second straight game on Sunday, losing 29-14 in Baltimore.
Kubiak says Schaub is "just banged up" and will likely sit out Wednesday's practice.
"We need him on the field," Kubiak said. "There's not a break in sight right now, it's a month away. We've just got to be smart with him. Throughout the week, if I've got to give him a break, a day a week, or two days a week. Matt can play without the practice."
Kubiak is hoping Andre Johnson can return this week after missing two games with a right hamstring injury. Johnson's workload will increase this week, Kubiak said, and his status for Sunday's game will be determined later.
Johnson was injured in Houston's 17-10 win over Pittsburgh in Week 4, and underwent a minor procedure to repair the hamstring.
"He made a lot of improvement last week," Kubiak said. "I had a long talk with him on Saturday night. He's feeling very, very good. I have a hard time saying (if he'll play Sunday). Maybe there's a chance he sees the practice field before the end of the week."
