The terms and length of Plackemeier's deal were not released.
Kyle Larson has been the Bengals' regular punter since 2004. In a similar move last February, Cincinnati signed free-agent punter Danny Baugher to a two-year deal, then re-signed Larson.
Larson averaged 39.5 yards a punt last season and twice tied a team record with 11 punts in a game. His 100 punts in the season broke the Bengals' record of 94 by Daniel Pope in 2000.
