With their wide receivers and defensive backs mostly healed, the Ravens' latest depth issue appears to be on the defensive line, where defensive tackle Timmy Jernigan, defensive tackle Christo Bilukidi, and defensive end DeAngelo Tyson missed practice Tuesday.
Jernigan missed practice for a second straight day with a foot issue, while Bilukidi is a new absence and Tyson hasn't practiced since Friday for undisclosed reasons.
Defensive end Brent Urban underwent surgery on a torn biceps muscle Tuesday, according to his Twitter account, leaving the team with just six defensive linemen: Lawrence Guy, Micajah Reynolds, Carl Davis, Kapron Lewis-Moore, Brandon Williams, and Chris Canty.
Williams said there's no concern among the position group that they might be light come the preseason opener.
"We're good," Williams said. "That's the coach's job to see how the rotation goes. We just come out there and play. That's all we're about."
Williams had praise for two of the players who expect to figure prominently in that rotation, Davis and Lewis-Moore. He called Davis a "raw talent" whom position coach Clarence Brooks is doing a good job molding, while Lewis-Moore is "doing a wonderful job" on his return from knee and Achilles injuries that cost him the last two seasons.
Williams said the opportunity for both to establish themselves begins Thursday.
"It's always good to have great film out there," he said. "Whatever happens, just having great film out there, and of course, the coaches can see what you can do. Kapron Lewis-Moore has been out for a few years, so putting some good film on and balling out like we know he can is going to be great for him."
Also missing were wide receiver Breshad Perriman (knee), guard John Urschel (concussion), and guard Robert Myers (concussion).
Safety Kendrick Lewis, who missed Monday with a leg issue, and cornerback Lardarius Webb, who left practice early Monday with a hamstring pull, returned Tuesday.
