The Dallas Cowboys signed linebacker Ray-Ray Armstrong and offensive lineman Wyatt Miller on Tuesday.
The moves came after the team placed linebacker Leighton Vander Esch and guard Xavier Su’a-Filo on injured reserve.
Vander Esch, the Cowboys’ 2018 first-round pick, will have surgery to fix a neck injury. He finished his second season with 72 tackles in nine games.
Su’a-Filo broke a bone in his lower leg during Sunday’s loss to the Philadelphia Eagles. He played in 11 games this season with four starts.
Armstrong has played for six teams over the last seven seasons, including five games with New Orleans earlier this year. He has 144 tackles and three interceptions in 83 NFL games (12 starts) with the St. Louis Rams, Oakland Raiders, San Francisco 49ers, New York Giants, Cleveland Browns and Saints.
Miller is an undrafted rookie from Central Florida. He was with the New York Jets during the preseason but did not make it through final roster cuts. He spent time on the Cincinnati Bengals’ practice squad.
Dallas (7-8) hosts the Washington Redskins (3-12) in Sunday’s regular-season finale. The Cowboys can still make the playoffs as NFC East champs if they beat Washington and if the Giants defeat the Eagles.
