The Cowboys bolstered their defensive line on Thursday by signing veteran defensive end Anthony Hargrove to a one-year deal. The Cowboys released guard D.J. Hall to make room for Hargrove, who will get the veteran minimum of $840,000 in 2013. He will count just $555,000 against the salary camp. Hargrove sat out the 2012 season after being suspended for the first eight games for his involvement in the New Orleans Saints bounty gate scandal. He was a member of the Green Bay Packers at the time of his suspension but was released before the season. No other team picked him up. Hargrove, a former third-round pick of the St. Louis Rams in 2004, was suspended for the 2008 season for violating the NFL's substance abuse policy. He played with the Saints in 2009 and 2010 before spending one year in Seattle in 2011.
