The Ravens have placed rookie wide receiver Darren Waller on injured reserve (IR) due to a hamstring injury. Waller marks the 12th Raven placed on IR.
The sixth-round rookie suffered the injury during Monday night's loss in Arizona.
Waller hasn't made much of an impact on offense, as he's notched two catches for 18 yards, but he's been one of the team's better special teams players.
His best play of the year on offense was a 17-yard catch in Pittsburgh that jumpstarted the Ravens' game-tying drive in the final minute. It helped Baltimore to its only win so far this season.
The 6-foot-6, 245-pound Georgia Tech product impressed in training camp and emerged from a competitive wide receiver competition to make the 53-man roster.
He was at or near the bottom of the pecking order, however, and didn't see much offensive action behind Steve Smith Sr., Kamar Aiken, Marlon Brown, Michael Campanaro (before going on IR) and, more recently, Chris Givens and Jeremy Ross.
The Ravens had a whopping eight receivers on the active roster, including injured first-round rookie Breshad Perriman. They're now down to seven.
Baltimore may have opted to place Waller on season-ending injured reserve because they needed to make room for an offensive tackle.
The Ravens promoted 6-foot-7, 326-pound offensive tackle De'Ondre Wesley from the practice squad. The undrafted rookie could be a necessary backup this Sunday against San Diego.
Starting left tackle Eugene Monroe suffered a shoulder injury late in Monday night's game and did not return, sending top backup James Hurst into action once again. Left guard Kelechi Osemele also left during the fourth quarter without returning because of a knee injury.
Baltimore signed another massive offensive tackle, Marcel Jones, to their practice squad. The former 2012 seventh-round pick spent last season on the Ravens* *practice squad, but didn't make the team out of training camp.
The Ravens also re-signed running back Terrence Magee to the practice squad. There was one open spot on the squad after wide receiver Jeremy Butler was promoted to the 53-man roster on Monday.
