Cornerback Jaire Alexander returned to the field Wednesday and was a full participant on Thursday, a positive sign that he'll be ready to make his gameday debut as a Raven.
Alexander managed his surgically repaired knee for much of August but has ramped back up into action with the regular season approaching.
Tight end Isiaah Likely (foot) and fullback Patrick Ricard (calf) are still not back at practice. Ricard hasn't practiced since Aug. 14, casting doubt on whether he'll be able to play in Buffalo.
The five-time Pro Bowler is a key blocker in the Ravens' rushing and sometimes passing attack, but Offensive Coordinator Todd Monken feels confident in Baltimore's answers if Ricard can't suit up.
Baltimore could elevate undrafted rookie fullback Lucas Scott from the practice squad, pivot to different personnel packages, or use tight ends Mark Andrews and Charlie Kolar in different ways.
"I feel good about our guys," Monken said. "The guys who will be suited up Sunday will be ready to go."
Bills Are Rushing to Get a Kicker Ready for Opener
The Bills are dealing with a spate of groin injuries and are breaking in a potential replacement kicker for Sunday's game.
Tyler Bass (left hip/groin) didn't practice Thursday after being limited Wednesday, and Buffalo signed veteran kicker Matt Prater to its practice squad.
Cornerback Tre'Davious White (groin) missed practice for a second straight day. Starting cornerback Christian Beford (groin) returned to full participation, but wide receiver Keon Coleman (groin) was still limited.
Monken's Focus in Buffalo Is 'Clean Football'
The Ravens outgained the Bills in total yards, passing yards, and rushing yards in their January playoff meeting. The two categories where they lost were turnovers (three) and penalties (five).
Monken made eliminating pre-snap penalties a focus this offseason and was happy with the progress he saw, particularly using cadence, after some hiccups early in camp.
He didn't have an explanation for why the Ravens turned the ball over so much in the playoff loss in Buffalo because they hadn't done so in other big games.
"We're pretty good when we play clean football. We really are," Monken said.
Zach Orr Pleased With Camp, Doesn't Expect Surprises
The Ravens' defense got off to a slow start last year, but Defensive Coordinator Zach Orr expects a stronger opener this year, both from his players and himself.
Orr said he's seen his players check off three important boxes with being on the same page, being aggressive attacking the football, and playing with consistent maximum effort.
"It's been one of the best camps that I've been a part of here," Orr said. "I'm very pleased with how that went."
Orr said his nerves might be a little different this time around, being that he's now in Year 2, but the biggest difference is that he's seen more football and expects it'll be harder for him to be surprised by what the Bills offense may try.
