The Dallas Cowboys have released defensive tackle La'Roi Glover and announced the retirement of linebacker Dat Nguyen. Glover, a 10-year veteran who signed with the Cowboys as a free agent in 2002, was cut Thursday. Glover made his sixth Pro Bowl last season, finishing with 26 tackles and three sacks. He has 71? career sacks, second all-time among defensive tackles behind Warren Sapp (84?). Glover had a career-high 76 tackles in his first season with Dallas in 2002, two years after he set a New Orleans record with 17 sacks. He had 21? sacks in four seasons with the Cowboys. Nguyen, an eight-year veteran out of Texas A&M, led the Cowboys with 172 tackles in 2001, his first full season as a starter. He was slowed by a neck injury last season, playing his last game Thanksgiving Day against Denver.
