SALT LAKE CITY (AP) — Hall of Fame quarterback Steve Young and his wife Barb are scheduled to give the keynote address at an upcoming conference promoting acceptance of gays and lesbians in the Mormon Church.

The couple's talk is set for Sept. 14, during the three-day Affirmation conference in Salt Lake City.

The Youngs are described as committed members of The Church of Jesus Christ of Latter-day Saints, and have been active on LGBT issues in the past.

They are longtime supporters of organizations including the Trevor Project, which provides crisis intervention for gay youth.

In 2008, Barb Young publicly lined up against California's Prop. 8, which defined marriage as between a man and a woman.

Young graduated from Brigham Young University and retired in 1999 after 13 seasons with the San Francisco 49ers.
