"I thought about it every once in a while. Thought about how I wanted to do it. When I could do it," Nassib said on the show. "I didn't know how people would react. I wanted to make sure I was financially stable before I did it. I didn't know if it would ruin my career. I didn't know if guys would be supportive or not."

Nassib said that he realized he was gay four years ago, and he didn’t want to come out right away because he was more focused on his career and establishing himself in the league. Nassib felt like it was his responsibility to come out and make it sociably acceptable in the locker room.

"When I decided to come out, it was not easy," Nassib said. "Personally, for my life, I didn't want to do it. But I felt a huge obligation to my community, to all the young kids out there who are struggling with their sexuality. If I could help just a few of them out, then I could sleep better at night."

Nassib, a Penn State product, is in his sixth season in the NFL and his second with the Raiders. He also spent time with the Cleveland Browns and Tampa Bay Buccaneers.

Before Nassib, no openly gay or bisexual player had previously played a regular-season down in the NFL. Michael Sam was openly gay when drafted out of the University of Missouri in 2014. But Sam never made a roster spot in the league.
