The New Orleans Saints shook up their secondary on Tuesday by placing cornerback Paulson Adebo on injured reserve, releasing Johnathan Abram from the practice squad and bringing back safety Roderic Teamer and cornerback Shemar Jean-Charles.

Saints coach Dennis Allen previously ruled Adebo out for the season after the cornerback broke his hamstring in last week’s loss to the Denver Broncos. But Abrams’ release is a mild surprise. Although the safety was not on the active roster, he had played a key role in filling in for starter Will Harris, who is on injured reserve with a hamstring injury.

Abram, a former first-round pick of the Raiders, played 12 games over two seasons for the Saints. This season, he played more than 60% of the snaps in his first two appearances before his role was significantly reduced in the final game. Abram played just 11 snaps against the Broncos, with second-year safety Jordan Howden getting the start alongside Tyrann Mathieu.

Teamer and Jean-Charles rejoin the training team after previously spending time with the team. Teamer, a fifth-year veteran who played 40 games with the Raiders, spent training camp with the Saints and was in the process of making the final roster. Jean-Charles played three games for the Saints last year in his fourth season and spent time on the practice squad.

In addition to the restructuring of the secondary, the Saints also announced the signing of wide receiver Marquez Valdes-Scantling and released guard Chris Reed from the practice squad.
