Baltimore Ravens head coach John Harbaugh admitted on Monday that he "hates" the fact that wide receiver Breshad Perriman, the franchise's most recent first-round pick, has been missing time during Ravens training camp due to an injury.  Perriman, a raw wideout from UCF who flew up draft boards after posting blazing 40 times, is set for an MRI this week to hopefully determine just what the issue with his knee is that has kept him off the field for Baltimore. The injury, per Jason Cole of Bleacher Report, has become quite "troublesome" for Harbaugh and the Ravens.

While Perriman likely needs as much practice time as possible if he's going to contribute this year, it's not just his own development that has the team worried, Per Cole, the Ravens consider both Marlon Brown and Kamar Aiken to be nothing more than "role players," which means that Baltimore is lacking offensive weaponry outside of the ageless Steve Smith.

The team was said to be high on Brown after the former undrafted free agent posted a promising rookie NFL season. In 14 games of work in 2013, Brown caught 49 balls for 524 yards and seven touchdowns. The Ravens expected even more out of the lanky wideout in 2014, but Brown ultimately failed to deliver, finishing the year with just 24 receptions for 255 yards and no touchdowns.

Considering deep threat Torrey Smith departed for the cozy confines of Southern  California this offseason, Perriman was expected to set right into his role as a field stretcher. Unfortunately, the injury to his knee has limited Perriman and now cost him 14 Ravens practices. While Aiken has been nothing but a special teamer to this point and Brown ultimately failed to secure a starting gig last year, Ravens fans may very well be looking at a wide receiver depth chart topped by a soon-to-retire Smith and a couple of guys who wouldn't even crack the top-53 on some teams.
