I very much expect this to turn into A Thing, because it always does, whether athletes miss a birth to play, or miss a game to be present for a birth.
On one hand, it's not like this is Flacco's first kid, and it's not like he can't have more. On the other hand, it's just the Browns.
But really, this is all Dana Flacco's fault. Why give birth on a football Sunday? (Woman can control that stuff, right?)
