The 6-foot-4, 285-pound Foster was waived with a ''failed physical'' designation. He joined the Saints as an undrafted rookie out of Illinois in 2013 and had three sacks in 12 games that season. Last season, he did not have a sack in five games and finished the season on injured reserve with a knee injury.
He had not practice at all this offseason and began training camp on the physically unable to perform list.
Manning is an undrafted free agent out of Northwest Missouri State who had tryouts in rookie camps with the Dallas Cowboys, Kansas City Chiefs and was later signed by the Green Bay Packers, but released shortly afterward.
