After spending the first six weeks of the regular season on the physically unable to perform list, linebacker Terrell Suggs is back at practice.
The Ravens activated him Wednesday and Suggs participated in the morning walkthrough at the team's training complex in Owings Mills.
Coach John Harbaugh cautioned that the team isn't looking too far ahead with the reigning Defensive Player of the Year as he continues to work toward a return from his Achilles tendon injury.
"To what extent, to what he's able to do, I think we should temper our expectations a little bit," Harbaugh said. "He's coming off a very serious injury. Until he's good, we'll just see how he does. So he will start today. This is the first time he's allowed to do it.
"I think he's worked really hard. He's done a great job with the rehab, he's followed protocol. He had no setbacks throughout the course of the whole deal, so that's a credit to him and to the doctors and to our trainers."
Harbaugh didn't have any idea when Suggs could return to game action, however.
"I don't have a timetable on that," Harbaugh said. "It's going to really be day to day. It really is."
Suggs declined to talk to the media, but is scheduled to do so Thursday.
In other news, the Ravens made an interesting decision regarding Ray Lewis, putting him on the designated to return list instead of officially shelving him for the season, as they did with Lardarius Webb.
Capitalizing on new NFL rules regarding injured reserve, Lewis must be out for at least six weeks and won't count against the team's 53-man roster for as long as he's out.
Harbaugh said that doesn't mean Lewis will return from his torn right triceps this year.
"We have no idea whether that timeframe has anything to do with the injury," Harbaugh said. "Obviously, it's a very serious injury, but there's an opportunity and we're going to keep the door open and we'll just see where that goes going forward. We really don't know any more than that."
The 37-year-old is undergoing surgery today. Normal recovery time for the surgery is up to six months.
Harbaugh also revealed that Webb has a torn left meniscus in addition to his torn ACL. The cornerback will undergo surgery today or tomorrow.
Linebacker Josh Bynes has been added to 53-man roster to take Lewis' spot while linebacker Nigel Carr and cornerback Jordan Mabin were signed to the practice squad.
