The injury is expected to sideline Jones for four to six weeks, a league source told Pro Football Talk.
Brandon Lloyd, Laurent Robinson and Austin Collie are the premier talents among the available veterans. While Lloyd has gotten nary a nibble on the open market, concussion risk Robinson remains unsigned after working out for a half-dozen teams since the end of the July.
Other available free agents include Braylon Edwards, Mohamed Massaquoi, Donte' Stallworth, Lavelle Hawkins and Michael Jenkins. If the Ravens place an emphasis on special teams, Josh Cribbs is out there.
