The Cowboys released veteran offensive guard Montrae Holland on Sunday, according to his agent, and they have signed Derrick Dockery to take his place. Dockery signed a one-year deal, according to his agent, Todd France.
Holland had missed most of training camp and the first three preseason games with a back injury. He played in Thursday's finale against the Dolphins, and owner Jerry Jones had praised his performance. Holland, 31, arrived in Dallas via a trade with the Broncos in 2008. He started four games in three seasons with the Cowboys.
Dockery is an eight-year veteran who is from Garland and the University of Texas. He had been scheduled to make a $3.82 million salary before being released by the Redskins in March. He was a third-round draft pick of the Redskins in 2003 before going to Buffalo as a free agent. Dockery, who turns 31 Wednesday, returned to the Redskins in 2009.
