Richardson and the Giants agreed to a contract Tuesday.
Richardson has been unable to make a roster since playing in 15 games with the Saints in 2015. He was most recently waived by the Broncos in May. The Giants are dealing with a variety of injuries on the defensive line, so Richardson should see a healthy workload at practice right away. However, his still figures to be a long shot for making the final roster.
Richardson was waived Wednesday by the Broncos, Cameron Wolfe of The Denver Post reports.
The Broncos opted to sign fellow defensive lineman Billy Winn earlier Wednesday, which left no room available on the roster for Richardson. The 24-year-old will look for a training-camp invite elsewhere, but may face an uphill battle to open the season on an NFL roster. His most recent action came with the Saints in 2015, when he played 15 games and recorded 40 tackles, 0.5 sacks and one interception.
Richardson signed a contract with the Broncos on Friday, Cameron Wolfe of the Denver Post reports.
Richardson spent 15 games with the Saints in 2015, recording 40 tackles, half a sack, one interception and a pass deflection. He'll look to compete for a spot on the Broncos' 53-man roster next season.
Saints DT Bobby Richardson made six tackles (two solo) in Sunday's win against the Cowboys.
Richardson, an undrafted rookie free agent out of Indiana, made his first career start in Week 4, after Akiem Hicks was traded mid-week to the Patriots.
While Richardson rotated playing time with another rookie, Tyler Davison, he was on the field for 38 of the Saints' 61 defensive snaps (62 percent), according to the New Orleans Times-Picayune. He made two tackles for a loss.
If Richardson can continue to hold down the starting gig, he could make an impact in deeper individual defensive player leagues.
