The Cowboys released defensive end Jason Vega to make room for defensive end Everette Brown, who agreed to terms Monday night.
The team also released running back Davin Meggett from the practice squad.
Vega played in two games after being signed off the practice squad Oct. 18. He played 46 plays total and made two tackles. He also was penalized twice for offsides.
Brown was a second-round pick of the Panthers in 2009. He has not played since the 2011 season when he was with the Chargers, though he went to training camp with the Eagles and the Lions since. Brown has played 31 games in his career with six career sacks.
The Cowboys still are discussing whether to place guard Brian Waters on season-ending injured reserve, according to a source. Owner Jerry Jones said earlier Tuesday that Waters torn triceps likely will cost the starting right guard the rest of the season, but Waters is exploring his options in what could be his last season.
