Per his usual policy, Browns coach Pat Shurmur didn't discuss injuries in his Wednesday press conference. He said Jackson was "in the building and all the meetings today" but chose to say "we'll see" when asked if Jackson would be at practice.
Jackson suffered a concussion during Sunday's loss to the New York Giants. Jackson will have to pass multiple concussion tests in order to play in Sunday's game against the Bengals.
Jackson was drafted by the Browns in the second round of the 2006 NFL Draft. Jackson missed most of the 2009 season, then missed the entire 2010 season with a torn pectoral muscle.
Through Cleveland's first five games this year, Jackson has registered 31 tackles, and has recorded three sacks. Jackson also has two interceptions and a fumble recovery.
