The Sun, citing league sources, reports that Jones had an MRI on Friday that revealed the injury. The Ravens will consider free agents to bolster their receiving corps, according to the report.
Jones walked off the field gingerly and was taken to the locker room for examination.
"That's an experience problem; he's an inexperienced guy," Ravens coach John Harbaugh said of Trawick after the game.
