Before Carl Nassib, Michael Sam was the NFL’s first openly gay draft pick. He never played a regular season game. – The Washington Post

Sam joined training camp with the St. Louis Rams but was ultimately cut. The Dallas Cowboys added him to a practice squad, but Sam’s position there lasted only seven weeks. He went on to play briefly for the Montreal Alouettes in Canada. But he never played in a regular season game for the NFL, and in 2015, Sam retired from football, citing mental health reasons.
