IRVING, Texas (AP) - The Dallas Cowboys have released guard David Arkin, who never played in a game after getting drafted in the fourth round two years ago.
Arkin was inactive all 16 games his rookie season and active but didn't play seven times last year. He was active just one this season, for the opener against the New York Giants.
The Cowboys filled Arkin's spot by activating safety Jakar Hamilton from their practice squad Saturday with rookie starter J.J. Wilcox out with a right knee sprain.
Hamilton is an undrafted rookie out of South Carolina State.
Jeff Heath, another rookie free agent, will start Sunday at Detroit in the place of Wilcox, who injured his knee in practice Thursday.
