At this point in the season, there's very little out there on the free agent market.
"There's really not a lot of guys out there," Harbaugh said. "If anything, people have been signing guys off their practice squads for about the last six weeks very aggressively. So unless a name comes before us which we have not seen yet, I would say that's probably not going to happen."
That will come as disappointing news to anyone hoping the Ravens would add a veteran wide receiver to bolster their inconsistent offense and a depleted receiving corps. With Anquan Boldin working his way back from knee surgery and David Reed now out for the season, the Ravens currently have only four healthy wideouts, three of whom are rookies.
One name which has gotten brought up by a number of fans is Derrick Mason, the veteran receiver who has pulled the rare and unenviable task of getting released by three separate teams (the Ravens, Jets and Texans) within a six-month span.
Mason, who is currently doing some TV work as an analyst for the NFL Network, is the Ravens' all-time leading receiver and has over 12,000 receiving yards in his career.
It doesn't look like the 37-year-old will be returning to Baltimore any time soon, however.
With Week 17 of the regular season upon us, the Ravens have to feel that their only choice is to go ahead with what they've got. Trying to bring in someone new and work them into the offense at this point in the year would be incredibly difficult.
The Ravens currently have one open roster spot after Reed was placed on injured reserve, and assuming Billy Cundiff is eventually able to return from his left calf injury, Shayne Graham will apparently be released, creating another opening on the 53-man roster.
GM Ozzie Newsome might add a fringe player or someone who can contribute on special teams, but those are his only real options right now.
