Texans left tackle Duane Brown, who hasn't missed a game because of an injury, has been bothered by a sore knee. He was kept out of the second half and was replaced by Rashad Butler. “It's the same pain I've had the last few weeks,†Brown said. “I couldn't push off. I didn't have any explosion. I'm going to get an MRI (today) and find out what's wrong with it.†Source: Houston Chronicle
