Michael Sam, the first openly gay player to be drafted by the NFL, tells Oprah Winfrey that he's heard from other gay men in the NFL.

On Saturday, cabler OWN: Oprah Winfrey Network will premiere Michael Sam, a 90-minute documentary on Sam's life.

The 24-year-old Sam, the SEC defensive player of the year in 2013, was cut by the St. Louis Rams before the start of the season. He then joined the Cowboys' 10-man practice squad, where he stayed for seven weeks before being let go.

In an exclusive interview to be broadcast following the film's premiere, Sam sits down with Oprah Winfrey.

In a sneak peek from the interview, Winfrey asks Sam, “Gay men in the NFL reached out to you and called you?” as Sam nods in agreement.

“They were thankful that I had the courage,” Sam answered. “They wished that they had the courage to come out.”

“There's a lot of us out there. I'm not the only one. I'm just the only one who's open,” he added.
