Who steps in for Baltimore's Jones?

Baltimore Ravens wide receiver/returner Jacoby Jones could miss four to six weeks after being diagnosed with a sprained MCL sustained in Thursday's loss to the Denver Broncos. Jones began the year as the Ravens' No. 2 receiver and the team is reportedly searching for replacements on the free agent market. Jones has made the most impact for the Ravens as part the special teams unit and the team may suffer the most in that area. Who are some possible replacements?
