Starting offensive guard Bobbie Williams has a swollen right ankle, and was granted a few days off by the coaching staff.
Williams' absence from the left guard spot today created a ripple effect of change and experimentation across the offensive line.
Bryant McKinnie lined up with the first-team offense at his old left tackle spot with Michael Oher shifting over to right tackle.
And rookie Kelechi Osemele, who's been lining up at right tackle with the starters, took over for Williams at left guard.
"That's what brings up this whole situation; we're going to get Bobbie two days of rest off that ankle," Ravens coach John Harbaugh said. "The ankle is swollen up. He's really been working hard. He needs it and it's going to be good for him. This gives us an opportunity to roll guys in at that spot and move some guys around. ..
"We're going to work different combinations. We're going to play guys at different spots. We want to make sure we don't miss anything."
Meanwhile, today marked the return of offensive lineman Jah Reid as he practiced for the first time since the spring when he initially sprained his right calf. Reid aggravated the injury shortly before the start of training camp, suffering a setback while working out.
Practicing with a protective black sleeve on his lower right leg, Reid made it through practice without incident.
"It's always great to play football," he said. "It's so much fun. I'm just glad to be out there with the team actually getting some reps, get some improvement and get ready for some of these preseason games.
"I'm still working on the calf, it's still healing. It's a slow process. I'm not taking as many reps as some of the other guys, but we just have to keep working. It's touchy here and there. I feel pretty good about it."
The former third-round draft pick, who was projected a potential starter at left guard during the offseason, operated at right tackle today with the second-team offense.
"I love playing right tackle," Reid said. "I love playing guard as well. I've always played right. It feels natural. Coming back from this injury, it's good to be at a place where I feel really comfortable."
Reid wasn't confident that he would definitely play in Friday night's preseason game against the Detroit Lions.
"I can't make any promises, but it's showing improvement," Reid said. "That's our goal, but we'll see how it goes."
The most difficult aspect of camp for Reid, a third-round draft pick from Central Florida who played sparingly as a rookie, has been remaining patient while his competitors are practicing every day.
"It's very tough," Reid said. "I waited to come back for so long, but you don't want anyother setback. You got to be patient, so that's what I've been doing."Copyright © 2014, The Baltimore Sun
