To make room for guard Ronald Leary, the Cowboys released wide receiver Anthony Armstrong on Saturday morning.
The Cowboys moved Leary from the practice squad to the 53-man roster because another team wanted to sign him. To protect Leary, whom the Cowboys value, they had to make this move.
It's doubtful Leary will be active Sunday when the Cowboys face the New Orleans Saints. The Cowboys now have 11 offensive linemen on their 53-man roster.
