Peyton Hillis re-injured his hamstring during practice on Friday. Hillis, who has missed Cleveland's past two games with the injury, will likely sit out Sunday's game at Houston. He had only returned to practice Thursday for the first time since last week. The Browns (3-4) had hoped he would be back to face the Texans and their No. 3 ranked defense. But it appears Hillis, who has rushed for only 211 yards amid weeks of distractions this season, will have to sit out another game.
