Texans' rookie left tackle Charles Spencer was lost for the season on Sunday. Spencer suffered a fractured tibia, the bone in his lower left leg, on a running play. He was replaced by Ephraim Salaam, a nine-year veteran who is playing in his first season with the Texans. "It's really sad," coach Gary Kubiak said. "The kid's going to be a great player. He needed this year. Now he's going to have to sit back and watch, but there's nothing you can do about it."
