Daughter wants to skip youth group for soccer tournament

She's a talented athlete and the soccer tournament is a big one. But it conflicts with youth group which has become really important to her faith. My wife thinks we should let her skip youth group this time but I'm worried about the message that sends about priorities. I don't want to be the overbearing parent but I also don't want her growing up thinking sports always comes first. How do you guys handle conflicts between activities and church commitments?
