The Seattle Seahawks could be missing three starting offensive linemen when they take the field against the Houston Texans on Sunday.

Right tackle Breno Giacomini and center Max Unger are both listed as doubtful to play against the league's second-ranked defense. Coach Pete Carroll said both would be game-time decisions but it looks unlikely either will be able to play.

Unger has a triceps injury the team is trying to be cautious with while Giacomini has a knee issue that worsened last week.

Left tackle Russell Okung is also out after being placed on the short-term injured reserve list last week with a sprained toe ligament.

Lemuel Jeanpierre would get the start at center in place of Unger with rookie Michael Bowie getting his first career start at right tackle.
