CINCINNATI -- The Bengals put center T.J. Johnson on injured reserve Saturday with an injured chest muscle, the latest setback to a team already depleted by injuries.
They signed running back Jarveon Williams off their practice squad.
Cincinnati (5-8) plays at Minnesota (10-3) on Sunday. The Bengals will be missing both starting cornerbacks -- Adam "Pacman" Jones and Dre Kirkpatrick -- along with three starting linebackers, including Vontaze Burfict.
Their weakened defense gave up a season-high in points to the NFL's lowest-ranked offense last Sunday, a 33-7 loss to the Chicago Bears at Paul Brown Stadium. A loss in Minnesota would give the Bengals their first back-to-back losing seasons since 2007-08.
Running back Joe Mixon also was ruled out on Saturday with a concussion.
