The Cowboys claimed guard Joe Berger off waivers from Miami and cut tight end Tony Curtis to make room on the active roster.
Berger, 6-5, 305 pounds, was a sixth-round pick of Carolina in 2005 and played in three games with the Dolphins last season but hadn't played in any games this season.
Berger is the second guard the Cowboys have picked up in the last two weeks, having also signed Travis Leffew off Green Bay's practice squad.
Curtis was called up from the Cowboys practice squad on Oct. 13 and played in four games. He was inactive against Indianapolis and Tampa Bay. If he clears waivers, he is eligible to return to the Cowboys' practice squad.
