Jackson suffered a knee injury in Saturday's preseason contest against Seattle and is questionable to return, Terry McCormick of TitanInsider.com reports.
Jackson played only three snaps on offense and didn't see a target before getting hurt. However, he made an impression on special teams with a 30-yard punt return. Jackson is battling for a spot on the 53-man roster with a host of other wideouts, including fellow returner Jha'Quan Jackson. As such, it could be a major blow to Kearis' chances of making the cut if the knee issue keeps him out of the Titans' final preseason contest Sunday, Aug. 25 against New Orleans.
