49ers Sign Former Bengals Draft Pick McKinnley Jackson

The San Francisco 49ers have signed former Cincinnati Bengals third-round pick McKinnley Jackson to their practice squad. Jackson came on late in the preseason for Cincinnati and flashed as a rookie with a sack and three tackles for loss in his final four games. San Francisco added the defensive tackle to provide size and depth to hold ground against the run ahead of their matchup with the Miami Dolphins.
