New Orleans has also made several other roster moves, including Wednesday's decision to place rookie safety Vinnie Sunseri on injured reserve. Saints coach Sean Payton says Sunseri fractured his forearm late in Sunday's loss to San Francisco. He was playing primarily on special teams before his injury.
Leonard played seven NFL seasons, including 16 games last season for Tampa Bay, and in 53 games with the Bengals - New Orleans' opponent Sunday - from 2010 to 2013.
