IRVING, Texas -- The Dallas Cowboys waived defensive end Michael Sam from their practice squad and signed linebacker Troy Davis.


Sam, the first openly gay player to be drafted, signed with the Cowboys on Sept. 3 after he was among the final cuts of the St. Louis Rams.


Coach Jason Garrett and defensive coordinator Rod Marinelli praised Sam's work in practice.


"Comes to work every day and practices hard," Garrett said last week. "One of 10 practice roster guys that we have, so he's working on his skills, trying to develop, but also doing a lot of other things. Playing offense, defense, playing the kicking game, that's what a lot of those guys do."


The Cowboys (6-1) have just seven sacks through seven games, but they never seriously considered calling up Sam to the active roster. With rookie defensive end DeMarcus Lawrence eligible to play Nov. 2 against the Arizona Cardinals, the Cowboys are hoping he can spark the pass rush.
