The Browns signed defensive back Derron Smith off the Bengals’ practice squad. The team waived defensive back Ibraheim Campbell with an injury designation in a corresponding move. The Bengals selected Smith in the sixth round of the 2015 draft. He appeared in 31 games with Cincinnati, making seven tackles, one pass breakup and six special teams tackles. He played three games this season before the Bengals cut him and re-signed him to their practice squad Nov. 7.
