OWINGS MILLS - Already shorthanded at inside linebacker, the Ravens will be without starter Jameel McClain for Sunday's game against the Broncos and possibly longer.
McClain has been ruled out of the game against Denver as a result of the neck injury he suffered during Baltimore's loss to the Redskins this past weekend.
X-rays on McClain's neck were negative, but Ravens coach John Harbaugh said the linebacker will undergo more tests on his neck and back to determine the severity of his injury.
McClain had started 42 straight games, including all 13 this season. His 79 tackles are third-most on the team.
With McClain sidelined, Baltimore could potentially be without its top three inside linebackers against the Broncos.
Dannell Ellerbe has missed each of the last two games with an ankle injury and his availability for Sunday is yet to be determined. Ray Lewis is eligible to be activated from the injured reserve - designated to return list this week, but is still less than two months removed from surgery to repair a complete tear of his right triceps and, like Ellerbe, his availability is yet to determined. Lewis returned to practice last week, but wasn't present for the portion of practice open to the media on Wednesday.
Harbaugh declined comment when asked his level of optimism that Lewis could play this week.
SUGGS PRACTICES: Outside linebacker Terrell Suggs practiced on a limited basis Wednesday as he continues to work his way back from the torn right biceps he sustained amid the Ravens' loss to the Steelers in Week 13.
Suggs was sidelined against the Redskins, but Harbaugh indicated Monday that Suggs has a "good chance" to play against the Broncos this weekend.
INJURY REPORT: Ellerbe (ankle), offensive lineman Marshal Yanda (ankle), fullback Vonta Leach (ankle), safety Bernard Pollard (ribs) and defensive linemen Arthur Jones (shoulder) and Pernell McPhee (groin/thigh) all missed practiced Wednesday.
Tight end Ed Dickson returned to practice on a limited basis, marking the first time he's practiced since spraining his right knee during Baltimore's win against the Chargers in Week 12. He's missed each of the last two games.
BROWN PROMOTED: Rookie safety Omar Brown was promoted from the practice squad to the active roster, filling the spot vacated by suspended cornerback Asa Jackson.
Jackson was handed a four-game suspension Sunday for violating the NFL's policy on performance enhancing drugs.
Brown recorded 10 tackles, an interception and two fumble recoveries during preseason with the Ravens. He also recovered an onside kick. Brown signed with the team as an undrafted free agent in early May.
Baltimore signed rookie defensive end/outside linebacker D.J. Bryant to replace Brown on the practice squad.
The Ravens are the fourth practice squad Bryant has spent time with this season after spending the preseason with the Texans.
Bryant entered the NFL as an undrafted free agent out of James Madison. A local product, he graduated from Randallstown High School in Baltimore in 2008.
Bryant posted three sacks during preseason with Houston. He had seven sacks en route to first-team All-CAA honors as a senior at James Madison.
