Rookie defensive end Michael Sam offiically joined the Dallas Cowboys' practice squad today after taking a physical.

Sam is the first openly gay active player in the NFL.

The St. Louis Rams cut the former Missouri All-American pass rusher on Saturday.

Sam recorded three sacks during the preseason, but was edged out for a roster spot by fellow rookie Ethan Westbrooks.

Sam was named the Southeastern Conference Co-Defensive Player of the Year last season.
