The Dallas Cowboys on Tuesday released Michael Sam, the first openly gay player to be drafted by the NFL.

Sam spent seven weeks on the Cowboys' 10-man practice squad.

The team said in a statement that they were making room for second-year linebacker Troy Davis.

“I want to thank the [Jerry] Jones family and the entire Cowboys organization for this opportunity, as well as my friends, family, teammates, and fans for their support,” Sam said in a series of tweets. “While this is disappointing, I will take the lessons I learned here in Dallas and continue to fight for an opportunity to prove that I can play every Sunday.”

Sam, a 24-year-old all-American defensive player of the year from Missouri, was invited to play for the Cowboys four days after the St. Louis Rams cut him from their roster.
