Ravens wideout Marlon Brown undergoes MRI for back issue

OWINGS MILLS, Md. — The Ravens continued to be shorthanded at the wide receiver position with Marlon Brown and Breshad Perriman once again sidelined during Wednesday’s practice.
Head coach John Harbaugh said Brown underwent a magnetic resonance imaging exam for a back issue that’s now cost him three practices in the first week of training camp. The third-year wideout sat out on Saturday and was limited during Sunday’s workout before sitting out the Ravens’ last two practices.
Brown initially twisted his back while reaching for a pass and aggravated it during Saturday’s practice.
“We were a little bit worried about it,” said Harbaugh about Brown undergoing an MRI. “There’s nothing in there as far as any kind of a disc [problem] or anything like that. There’s a nerve root issue of some kind. I don’t know how long it’s going to take. I hope not very long.”
Perriman missed his fifth consecutive practice while dealing with a knee sprain suffered on the first day of full-squad workouts. Harbaugh initially projected the 2015 first-round pick to only miss a day or two of practice, but the Ravens are being conservative with his knee.
Those injuries have left the Ravens without two of their top four projected receivers as they continue to adjust to new offensive coordinator Marc Trestman’s system.
“It’s just how he gets the range of movement going in there with the bruise and everything like that,” said Harbaugh, who estimated it will take a couple more days until Perriman returns. “I’m anxious. I want him out here right now. He wants to be out here, but [the trainers] are holding him back. It’s probably smart. They’re smarter than Breshad and I are about it — I know that.”
Linebacker Elvis Dumervil returned to the practice field after missing four straight days with Achilles tendinitis. The veteran pass rusher was limited during Wednesday morning’s workout.
Cornerback Rashaan Melvin (hamstring) also returned to practice while fellow cornerbacks Tray Walker (hamstring) and Chris Greenwood are “close” to returning to practice, according to Harbaugh. Outside linebacker Zach Thompson also sat out Wednesday’s practice.
Offensive lineman Ryan Jensen tweaked his foot on Wednesday and will be evaluated further, according to Harbaugh.
The Ravens also made a roster move on Wednesday, waiving defensive tackle Casey Walker and signing Micajah Reynolds. Walker had just been activated from the physically unable to perform list on Monday while Reynolds spent last summer with the Miami Dolphins.
