David Archuleta is a man on a mission. Or at least he will be soon. And that could make for some disappointing news for his fans.

The "American Idol" favorite announced during his concert on his home turf of Utah Sunday night that he's putting his music career on the back burner -- so that he can serve the Mormon Church on a full-time mission.

"While I'm home in front of you guys tonight I would like to make a special announcement that I've chosen to serve a full-time mission," Archuleta told the crowd at his Salt Lake City show during an emotional announcement that found the singer breaking down in tears.

The 20-year-old singer added, "It's not because someone told me I was supposed to do it, not because I no longer want to do music anymore, but it's because it's the feeling that I feel I need to do next in my life."

The downside? Since a Mormon mission lasts two years -- and the church instructs missionaries to "avoid all forms of worldly entertainment" -- it looks like there won't be any new tunes coming from Archuleta in the near future.

The good news? Archie just might show up on some lucky fans' doorsteps as he spreads the good word.
