NFL commissioner Roger Goodell today spoke. NFL spokesman Greg Aiello posted the comments in a tweet:

Good for him. He's proud of who he is & had the courage to say it. Now he wants to play football. We have a policy prohibiting discrimination based on sexual orientation. We will have further training & make sure that everyone understands our commitment. We truly believe in diversity & this is an opportunity to demonstrate it.

Goodell has a gay brother, who has called Sam a "hero."
