Doug Pensinger/Getty Images Already thin at targets for Joe Flacco, the Baltimore Ravens will be without wide receiver Jacoby Jones for 4-6 weeks with an MCL sprain. An MRI conducted on Jones revealed that he sprained his medial collateral ligament according to the Baltimore Sun. The injury occurred when teammate Brynden Trawick ran into Jones who was calling for a fair catch early in the Ravens Thursday night loss to the Denver Broncos. Jones is expected to miss four-to-six weeks. Last season Jones caught 30 passes for 406 yards and a touchdown but was a key contributor on special teams returning 37 punts for 341 yards and a touchdown. Jones also recorded two touchdowns on kickoff returns.
