"When Andre's on your team, everybody tries to take him away," Kubiak said Wednesday. "Like I said, we can't replace Andre. We've got to, as a group, try to replace all the production that he adds on the field. That means everybody's got to pick it up, and we'll have a chance to prove it."
Johnson was hurt during the second quarter of Sunday's 17-10 victory over the Pittsburgh Steelers. Kubiak wouldn't put a timetable on Johnson's return after Tuesday's procedure, but the coach said "everything went well."
Johnson leads the Texans with 25 catches for 352 yards, but the team can rely on several other playmakers to distribute the load.
"I think, if anything, it will distribute the ball more because he (Andre) gets open all the time," Dennison said.
Houston also might be without backup running backs Ben Tate (groin) and Derrick Ward (sprained right ankle) against Oakland. Tate and Ward both sat out practice Wednesday, but Kubiak was hopeful that Tate would be ready by Sunday.
