Edwards’ season is over because of a back injury incurred against the Minnesota Vikings. The former second-round draft pick is scheduled to be an unrestricted free agent at the end of this season.
The fifth-year pro started a career-high 13 games last season when Trevor Pryce was injured and recorded 58 tackles to rank ninth on the team.
"Dwan Edwards is a big loss for us, because he’s a big part of our rotation," Ravens coach John Harbaugh said. "He is really coming on as a football player. That was a disappointment. That hurt us a little bit."
Edwards was held out of a loss to the St. Louis Rams over the weekend. He had posted six tackles and a sack in the first two preseason games prior to the discovery of the back ailment during a magnetic resonance imaging exam.
"Dwan had an ongoing thing where he was feeling a little bit of tightness there," Harbaugh said. "They did an MRI just as a precautionary, and they caught something, which is really fortunate and a great job by our medical team.
"As a result, he’s going to be out for the year until he can correct it. He’ll play again, but it’s going to take a good part of this year to correct it. It’s not something you can take a chance with and let it slide."
Former second-round draft pick Dan Cody is expected to pick up the majority of Edwards’ playing time in the rotation upfront. He returned last week from a sprained foot that kept him out three weeks, recording a tackle in the fourth quarter against the Rams.
"I feel good," Cody said. "I’m ready to get out there and run around and make some plays."
Meanwhile, the Ravens cut former Washington Redskins and Philadelphia Eagles wide receiver Darnerien McCants (Arundel) and tight end Aaron Walker.
Linebacker Terrence Melton, who injured his hand during his second practice with the team, and nose guard Kelly Talavou (dislocated shoulder) were placed on injured reserve.
Down to the league limit of 75 players, the Ravens have until Saturday to trim their roster to 53 players.
"Most of the guys had issues with injuries and weren’t really playing for us at this point anyway," Harbaugh said of the moves. "So, I don’t think it makes much of an impact. Although they were good players that we had high hopes for, with the nicks, they never really had the chance to prove themselves."
ON THE MEND: Activated from the physically unable to perform list after passing his physical, wide receiver Demetrius Williams is hoping to resume his big-play form.
The 6-foot-2, 197-pound former fourth-round pick caught 22 passes for 396 yards last season despite missing seven games with a high-ankle sprain, leading the team with 18 yards per catch. He caught two touchdowns, including a 77-yard effort.
"I don’t want to miss any games like last year," Williams said. "Right now, it’s coming day by day. These last few days I’ve been out there practicing and doing a lot better and feeling good."
Williams was sidelined with a sore left Achilles’ tendon, the same injury that limited his participation at offseason minicamps. Now, he’s trying to build chemistry with rookie quarterback Joe Flacco.
"You want to be in there to make the plays and get the quarterback relationship, but you don’t want to go out there and do something to yourself that is detrimental," Williams said. "I’m definitely being smart this time."
INJURY REPORT: Rookie linebacker Tavares Gooden (concussion) returned to practice.
Cornerback Chris McAlister was wearing a right knee brace and Frank Walker was lining up with the first defense in his place opposite Samari Rolle. McAlister was limited to individual drills.
McAlister has yet to play in the preseason.
Defensive tackle Haloti Ngata has been limited due to a sprained right medial collateral ligament.
"The coaches are being careful with it," Ngata said. "They want to be sure it’s 100 percent."
Not practicing: cornerbacks Fabian Washington (hamstring) and Derrick Martin (right shoulder), quarterbacks Troy Smith (illness) and Kyle Boller (right shoulder), free safety Ed Reed (left shoulder), running back Willis McGahee (left arthroscopic knee surgery), nose guard Kelly Gregg (left arthroscopic knee surgery) and wide receiver Marcus Smith (separated right shoulder).
