ANNAPOLIS - Arthur Jones is far from the most high-profile name on the Ravens' defensive line.
But he started to emerge as a valuable contributor about midway through last season, and a more toned up Jones has impressed teammates and coaches with his play through the early part of training camp this summer.
"Art's having a tremendous camp. He really is," Baltimore coach John Harbaugh said. "He's quick. He's fast. He's playing with better technique than he's ever played with. Art's having his best camp [that he's had]."
Jones, a fifth-round pick of the Ravens in 2010, had 47 tackles and 4.5 sacks during the regular season last year and had nine tackles and a sack in Baltimore's four playoff games, but he feels like he's poised for an even better season this year.
Jones has been consistently listed around 315 pounds in the past.He said he still weighs 315 now, but he's noticeably trimmer and said he lost some body fat leading up to training camp.
"I feel great," Jones said. "I feel like I'm a lot more explosive. And even aside from that, I feel like I'm playing better with better technique and being more consistent. That's the main thing I've been working on: Not being flashy, but just being consistent, being consistent play in and play out."
Jones, Haloti Ngata and free-agent addition Chris Canty have been the three primary fixtures on the Ravens' first-team defensive line through this point of training camp.
"He's been getting off the ball pretty good," Baltimore left tackle Bryant McKinnie said of Jones. "He's been playing well, too. This is his fourth year now. And usually when players get into their fourth and fifth year, they start to turn it on a little bit, and I think that's what he's doing."
DICKSON HURT: Ravens tight end Ed Dickson left Sunday's practice early with a hamstring injury and didn't return, but Baltimore coach John Harbaugh made it seem after practice like Dickson's injury is considered minor.
"His hamstring grabbed a little bit, so we pulled him out for precautionary reasons," Harbaugh said. "We'll take a look [Monday] and see how it looks."
IHEDIGBO DOESN'T PRACTICE: Safety James Ihedigbo, currently listed as Baltimore's starter at strong safety, didn't practice Sunday after injuring his neck late in Friday's practice.
But, like Dickson's, Ihedigbo's injury isn't considered serious.
"I'm still kind of sore, but it's just a minor neck injury," Ihedigbo said. "I'm just letting it settle down and doing what I'm being told. The doctors said to take the day to let it settle down, and that's what I'm doing. I'll be back out in no time."
