IRVING, Texas – The Dolphins signed guard David Arkin from the Cowboys' practice squad.
The 2011 fourth-round pick from Missouri State was released by the team on Oct. 26 to make room for safety Jakar Hamilton on the 53-man roster. Arkin then returned to the Cowboys' practice squad two days later.
Arkin was inactive for six of his seven games this year on the 53-man roster and never played in a regular season game for the Cowboys. He appeared to be taking strides this preseason from where he was at in past years.
Given the recent goings-on in Miami and the suspension of offensive lineman Richie Incognito, the Dolphins are looking for all the depth they can get.

The Cowboys also parted ways Tuesday with defensive tackle Marvin Austin, who was waived/injured.
Austin signed with the Cowboys on Oct. 21 and played that weekend against the Lions, finishing with a tackle. He was unable to push through a back injury Sunday against the Vikings that bothered him in practice late in the week.
