Ravens notebook: Cousins to stay at right guard
For now, the Ravens plan to keep Oniel Cousins at right guard.

Coach John Harbaugh confirmed that moving forward, Cousins, a converted offensive tackle, will remain at right guard, which likely means rookie Jah Reid will continue to start at right tackle.

"I think we will put him [Cousins] in there at guard, leave him in there and see how he does," Harbaugh said after the team's practice Sunday in Owings Mills. "It's a good point. He was comfortable in there. He's a big, strong man. That bodes well at guard. He is a good bender. He has got a lot of reach, and it worked out for him in there."

Cousins was flagged for a false start Friday night but also made the block that opened the hole for running back Ray Rice's 26-yard touchdown run in the second quarter of the Ravens' 31-13 win over the Kansas City Chiefs.

Marshal Yanda, the usual starter at right guard, returned to the field Sunday for the first time since the Ravens' preseason opener against the Philadelphia Eagles on Aug. 11, but his appearance was brief. After participating in individual exercises, Yanda (back spasms) left and did not return.

Harbaugh also updated the status of center Matt Birk, who underwent surgery on his left knee Aug. 2.

"He is progressing," Harbaugh said. "It was supposed to be three to four weeks before he would be moving around pretty well. Now he is starting to walk a little bit. I want to see him out there sooner rather than later, but it's not something that we really control."

Perhaps because of the fluctuation along the offensive line, the club signed offensive tackle Mark LeVoir and center Jason Murphy to the roster before Sunday's practice.

LeVoir is a five-year veteran who had spent the previous three seasons with the New England Patriots. Harbaugh said LeVoir's experience under Patriots offensive line coach Dante Scarnecchia was a major draw.

"That's a big plus," Harbaugh said. "[LeVoir] understands NFL defenses, and that's what we need right now. It was a fortuitous situation for us, and we'll see how he does."

Murphy, a Baltimore native and Edmondson graduate, has spent time on the practice squads of the Tennessee Titans, Seattle Seahawks and San Diego Chargers. Murphy, 6 feet 2, 310 pounds, joins a group of centers that includes Bryan Mattison and rookies Tim Barnes and Ryan Bartholomew.

To make room for LeVoir and Murphy, the Ravens waived guard-tackle Kyle Calloway and rookie guard Colin Madison.

Carr: hamstring 'progressing'

Chris Carr returned to practice, but the cornerback is still working on returning to full strength.

Carr suited up for the first time since tweaking his left hamstring Aug. 14 and took part in some individual exercises, but he was kept out of team drills. Carr, who sat out Friday night's game, said his limited appearance was part of his rehabilitation.

"I don't want to talk too much about the injury, but I'm still progressing," he said after Sunday's practice. "I'm still working on it."

Lewis returns to practice

In addition to Yanda and Carr, the Ravens welcomed back inside linebacker Ray Lewis, who had been excused from the team's practice Wednesday and the game against the Chiefs to deal with an aunt's serious illness.

"It's great to have Ray back," Harbaugh said, "to walk in this morning and see him sitting in his usual seat. … It's Sunday today, so we had a little prayer blessing, and he did it for us. Ray is our leader, so it is great to have him here."
