The Cowboys have traded for offensive lineman Ryan Cook, giving the Miami Dolphins a seventh-round pick in 2013. Cook was expected to be among the Dolphins' cuts today, but by trading for him, the Cowboys assure themselves of getting a veteran who can play the interior of the line.
Cook, a second-round draft choice of the Vikings in 2006, has played tackle, guard and center. The Dolphins acquired him off the waiver wire last year, and he played guard and center for them in 2011. He was beaten out by undrafted rookie Josh Samuda for the backup center spot in Miami.
Cook, scheduled to earn $1 million this season, has started 40 games, mostly at right tackle, but he also has started games at right guard and at center.
The Cowboys have been thin in the interior of their line because of injuries. David Arkin, who had never played center, started the first three preseason games in place of Phil Costa, who has been slowed by back pain. Backups Bill Nagy and Kevin Kowalski had ankle injuries in camp that prompted the Cowboys to waive/injured Nagy, who was claimed by the Lions, and place Kowalski on the reserve physically unable to perform list. Kowalski will miss at least the first six weeks of the season.
