Texans notes:Banged-up players expected to play against the Bills

Because receiver Andre Johnson didn't practice Wednesday, André Davis was working with the first team opposite Kevin Walter. Johnson expects to play at Buffalo, but Davis is getting ready just in case.,,,,,The Texans average 79.1 yards rushing. The Bills allow 172.4 yards rushing, including 5.2 yards a carry. They play very hard, and they're very aggressive,? left tackle Duane Brown said about the Bills' run defense. ?Whatever they've done up to this point really doesn't matter. I'm sure they know we haven't run the ball as well as we'd like to, so they're going to want to take advantage of that as well.? Houston Chronicle
