Jacoby Jones has been diagnosed with a knee sprain that could keep him off the field for up to six weeks, according to reports.

The wide receiver sustained the injury during the Baltimore Ravens' 49-27 loss to the Denver Broncos on Thursday night when teammate Brynden Trawick ran into him during a punt return.

NFL.com has reported that Jones has an MCL sprain, while Pro Football Talk says that he is expected to miss four to six weeks.

Meanwhile, the Baltimore Sun claims that Ravens general manager Ozzie Newsome will attempt to bring in a free agent wideout to fill in for the 29-year-old.

The Ravens will face the Cleveland Browns next weekend.
