The New England Patriots’ practice squad had three openings, and now they have been filled.

On Wednesday, the team announced the addition of cornerbacks Justin Green and Daxton Swanson, as well as linebacker Deontae Skinner to the 10-man roster. All three are in return trips to the Patriots.

Green, 23, originally signed with New England as an undrafted free agent in July of 2013, and spent much of his first NFL season on the team’s practice squad. The 5-foot-11, 195-pound Illinois product played in two regular-season games last year, but on Aug. 12 of this year, Green was traded to the Dallas Cowboys in exchange for defensive lineman Ben Bass. Green was subsequently waived by Dallas on Sept. 1, and was in for a tryout with the Patriots later on that month. Green had been slated to join the San Jose SaberCats of the Arena Football League for the 2015 campaign.

Swanson, 23, entered the NFL as an undrafted rookie by way of Sam Houston State in 2013, spending his inaugural season between the Indianapolis Colts’ injured reserve list and the San Francisco 49ers’ practice squad. The 5-foot-11, 195-pound corner was released by the 49ers on May 12 before joining the Patriots 10 days later. Swanson remained with New England through August and signed to the practice squad on Sept. 1. He was released on Sept. 3 and re-signed on Sept. 17, prior to being released again on Nov. 26.

Skinner, 24, arrived in Foxborough via Mississippi State after going undrafted in May. The 6-foot-2, 250-pound inside linebacker was released by the Patriots during the 75-man roster cutdown on Aug. 26, ultimately returning on the practice squad six days later. Skinner was promoted to the 53-man roster on Sept. 13 and went on to play in seven games, recording one start, 10 tackles, three special-teams stops and one sack this season. The undrafted rookie was waived on Oct. 29 and re-signed to the practice squad on Oct. 31. He was released along with Swanson on Nov. 26.
