OWINGS MILLS - The Ravens may be without Pro Bowl running back Ray Rice for at least one more game.
Rice appeared to be on track to being available for Sunday's game against the Buffalo Bills, but it now looks likely that Rice will be sidelined for the second straight game as he continues to work back from the strained hip flexor he suffered against the Cleveland Browns in Week 2.
Rice practiced on a limited basis for the third straight day Friday, but Baltimore coach John Harbaugh and Rice both seemed skeptical regarding Rice's chances of playing when speaking after practice.
Rice is listed as questionable for the game, but Harbaugh said prior to the injury report being released that there was a chance Rice could be listed as doubtful.
It will be a game-time decision.
"There's a chance that I could be out there on Sunday," Rice said. "I just obviously have to go out there and warm up and see how it feels out there and let the coaches make the decision from there."
Rice did say that it was encouraging to make it through a full week of practice.
"There's no way I would go out to practice without being able to practice," Rice said. "I'm not just a standing monument out there. So, what I did was, I pushed myself to a limit where I would feel was good enough ... and I was able to go throughout the week.
"The biggest thing with my kind of injury is more just your leg getting tired. It's not where it's at physically. It's more the fatigueness of it, so I was able to sustain a whole level of practice ... so that was a good sign."
If Rice is unable to go, Bernard Pierce, as he did last week, will handle the majority of the workload against Buffalo and a Bills run defense that ranks among the worst in the NFL.
SET TO DEBUT: Ravens rookie defensive lineman Brandon Williams appears set to make his NFL debut Sunday.
Williams, Baltimore's third-round pick in this year's NFL draft, missed the first three games of the season while recovering from a toe injury, but he has practiced on a limited basis the last two weeks and expects to play on Sunday.
"I'm doing good, feeling really good," Williams said. "The foot's feeling really good, so I should be good to go on Sunday."
If Williams does end up playing, he could see a decent workload with backup nose tackle Terrence Cody injured and unlikely to play.
Williams is officially listed as questionable for Sunday.
OTHER INJURIES: Rice and Williams were just two of eight Ravens listed as questionable for Sunday's game versus the Bills.
Like Rice and Williams, starting defensive end Chris Canty (groin), inside linebacker Arthur Brown (chest), wide receiver Deonte Thompson (foot), outside linebacker Pernell McPhee (knee) and running back Shaun Draughn (ankle) were all limited in practice throughout the week and are questionable for Sunday.
Meanwhile, wide receiver Brandon Stokley was added to the injury report with a groin injury Friday and is also listed as questionable.
Wide receiver Marlon Brown (neck) was a full participant in practice for a second straight day Friday after not practicing Wednesday. He's listed as probable.
Cody (knee) and center Ryan Jensen (foot) are doubtful.
For Buffalo, defensive end Mario Williams (ankle), running back C.J. Spiller, defensive tackle Kyle Williams (Achilles), wide receiver Stevie Johnson (hamstring), right guard Kraig Urbik (knee) and defensive tackle Marcell Dareus (ankle) are all probable, but cornerback Leodis McKelvin (hamstring) and Pro Bowl free safety Jairus Byrd (foot) are both questionable and appear unlikely to play.
