Kubiak suffered a 'mini-stroke' during a game with the Indianapolis Colts at the start of the month, resulting in some time in hospital.
Despite a return to team duties, Kubiak has watched the last two Texans games from a booth rather than on the sidelines. However, he is hopeful that will change this Sunday when they take on the New England Patriots.
Kubiak told the club's website: "I have every intention of being on the field. I hope the doctors clear me. I think I've got probably a better chance than I had last week. That's the way I'd answer that question right now."
With the Texans currently on a nine-game losing streak, Kubiak's position as coach has come under threat in recent weeks.
The team sits bottom of the AFC South with a 2-9 record.
