Running back Chris Brown was available but not feeling well and didn't play in Houston's 29-6 victory. Linebacker Xavier Adibi also was ill but played on special teams.
Offense lineman Eric Winston said Wilson was so sick that he "could barely walk."
"Some guys can play through it," Winston said. "It all depends on how it affects you. You are always concerned about some outbreak of the flu. If we get it, we get it. We just have to get over it."
When asked if the illnesses were more cases of swine flu, Kubiak said: I don't want to speculate on any of that ... but it was kind of scary (Sunday) morning, to be honest with you."
