Cornerback Marcus Peters (calf) and defensive tackle Calais Campbell (knee) has also been ruled out after leaving last week’s game in Cleveland with injuries. Neither practiced all week.
Defensive Coordinator Mike Macdonald said Wednesday that he feels confident in Brandon Stephens stepping in for Peters.
“He goes out there and competes. There are some situations where he’ll win some, lose some, but the guy is out there, and he’s battling, and he knows what to do, he’s very conscientious,” Macdonald said. “We expect him to go out there and not miss a beat.”
On the defensive line, the Ravens will need more across the defensive line from Justin Madubuike, Travis Jones, Broderick Washington and Brent Urban. Urban is Campbell’s backup on the depth chart.
Left tackle Ronnie Stanley (ankle) did not practice Tuesday or Thursday but enters the game without an injury designation, so he should be good to go.
Harbaugh said the Ravens are “planning on playing” wide receiver Sammy Watkins, who was claimed off waivers this week. Watkins already has familiarity with the scheme and playbook from his time with Baltimore last season.
The Falcons enter the game healthier than the Ravens. They only ruled out backup offensive tackle Chuma Edoga (knee).
