Davis (quadriceps) has been ruled out for Sunday's game against the Ravens.
Davis was held out of practice all week, which isn't a great sign given that he was designated to return from injured reserve Oct. 6. If he's not activated from IR by the end of his 21-day window, then Davis would be required to miss the rest of the season. His next chance to play is Week 7 against the Titans on Sunday, Oct. 25.
