The Cowboys re-signed OG Montrae Holland to replace starting OG Bill Nagy, who was placed on injured reserve, according to ESPN Dallas.
Holland played in 14 games with two starts for the Cowboys last season. He spent the last four seasons in Dallas and started all 16 games in 2007. Holland began his career in New Orleans and has 50 career starts.
Nagy broke his right ankle in Sunday's loss to the Patriots. The rookie had been starting at left guard and was replaced by another rookie, Kevin Kowalski. Veteran OG Derrick Dockery was out with a sprained MCL.
