Jackson (knee) did not practice Thursday, Alaina Getzenberg of ESPN.com reports.

EDGE Analysis

Jackson's injury appears to be a new one, as he was seen wearing a sleeve over his left leg on the sidelines. The third-year pro was a standout in camp and earned a starting job at corner, at least while Tre'Davious White (knee) is out of action. If Jackson is unable to go Sunday against the Titans, it could lead to rookies Kaiir Elam and Christian Benford both getting the start.
