A co-worker just pointed me to this article:

Nothing shocking, I guess, but it's good to know that one or two days of rest when you start to experience symptoms isn't enough ... that it's okay to take it easy on days when you're feeling less than 100% ... that they recommend at least (!) two days of rest a week. It makes me feel less like a slacker that in the last seven days, the only thing I've done is played 1.5 indoor soccer games ... I'm not slacking, I'm recovering from overtraining!
