Ravens backup nose tackle Terrence Cody headed to the locker room in the first quarter with a sprained left knee and didn't return to the game.
Cody went down to the ground during the Texans' opening offensive drive and trainers immediately attended to him. He was helped off the field to the bench, where his left knee was examined. He was able to limp into the locker room under his own power.
"It does not look to be a long-term sprain," Ravens coach John Harbaugh said of Cody. "It could be this week, but more likely it will be a couple weeks. We'll see."
"I don't know the severity of it, but it's termed right now as a high ankle," Harbaugh said of Draughn.
Draughn told The Baltimore Sun that the injury initially doesn't seem that serious.
"I had one before, and that's what it felt like," Draughn said. "The pain was moving around. It don't feel too bad right now. I think I'll be back next week, I'll be good. I might have to take off Monday and Tuesday."
