Michael Sam, the first openly gay player taken in the NFL draft, celebrated the moment the way other football players have celebrated: by kissing the person he is in a relationship with.

The NFL’s historic moment was filmed by ESPN and, as St. Louis Rams Coach Jeff Fisher told him the news over the telephone, Sam broke into tears and sobbed. Then he embraced and kissed his boyfriend as they shared cake.
