Because the Miami Dolphins are running short on offensive guards the team swapped out an offensive tackle for an offensive guard on Thursday. The Dolphins, who are practicing without Lance Louis, who is rehabbing a surgically repaired knee, and rookie Dallas Thomas, who is rehabbing a surgically repaired right shoulder, released Patrick Ward to make room for Brian Thomas. Thomas, a 6-foot-3, 315-pound rookie, played at Texas A&M most of his collegiate career. He transferred to Texas Tech for his senior season, but did not play for the Red Raiders. However, in 2010 Thomas started all 13 games for the Aggies, which were then coached by Dolphins offensive coordinator Mike Sherman. Ward, a former Northwestern standout, was signed by Miami as a rookie free agent this offseason. The Dolphins have six offensive tackles on the roster, but very few healthy guards.
