The Saints signed center Ryan Groy and safety Terrell Williams, according to a team announcement. In related moves, the club released guard Mike Herndon wide receiver Micah Wright, and tackle Derek Newton. 
Groy, 29 in September, spent the last four years with the Bills and made 14 starts over the last three seasons. The Bills kept him from joining the Rams by matching his offer sheet a couple of years ago, but they did not make a strong push to retain him this time around.
Newton, meanwhile, is being bumped to make room for new arrival Marshall Newhouse. The longtime starter for the Texans hasn’t been the same since he tore both patellar tendons in a 2016 game against the Broncos. He tried to rekindle his career with the Saints, but he leaves the team after suiting up for just one game.
