Receiver Anthony Armstrong tweeted "the grind doesn't stop here" after he learned of his release from the Cowboys.
Armstrong's depature likely means the Cowboys will keep five receivers to start the season. Injuries at other positions likely cost Armstrong. He is an immediate free agent, but if he doesn't land with another team, Armstrong could return in Week 2, when his season salary would not be fully guaranteed.
Armstrong has been cut by the team two other times since Dec. 22 and re-signed twice. He has played in one game for the Cowboys, getting in against the Steelers last year.
Receivers Dez Bryant, Miles Austin, Dwayne Harris, Terrance Harris and Cole Beasley will make the roster.
The Cowboys are in the process of reducing their roster from 75 to 53. They have until 5 p.m. Saturday.
Defensive tackle Sean Lissemore, guard Nate Livings, tackle Demetress Bell and safety Matt Johnson are among the biggest names on the bubble.
The Cowboys will release quarterback Alex Tanney, whom they could re-sign to the practice squad if he clears waivers.
