IRVING, Texas - Michael Sam will have to wait for a third team to give the NFL's first openly gay player a chance to appear in a regular-season game.

The Dallas Cowboys released Sam from the practice squad Tuesday, dropping the defensive end as they prepare for several potential reinforcements to return to the defensive line.

Sam spent seven weeks with the Cowboys after joining their practice squad Sept. 3, four days after he was among the final cuts by the St. Louis Rams at the end of the preseason. He was never placed on the 53-man active roster.

The Rams drafted Sam in the seventh round in May. He was pick No. 249 out of 256. Sam had three sacks in the preseason with St. Louis playing mostly against second- and third-stringers.

Sam thanked the family of Cowboys owner Jerry Jones on Twitter, along with "friends, family, teammates, and fans for their support."
