Linebacker Darryl Sharpton, signed Wednesday, is the ninth new player to be added to the 53-man roster since facing the Bills. Sharpton spent the last four seasons with the Houston Texans, playing under Bears linebackers coach Reggie Herring for the last three. He has the ability to be a backup at all three positions and should be able to help on special teams. He's the second linebacker to be added to the mix after Terrell Manning was promoted from the 53-man roster just prior to Monday's game at MetLife Stadium.
