Exactly. You don't even owe her a phone call and you certainly don't owe her any explanation as to why an absent-but-possibly-en route player would be placed at the bottom of the lineup. It's unfortunate for the child, but she's off your fall team and I would doubt you'd want to take her on again in the spring, unless she gets a new mom.
Agree 100%. I would just consider her career with my team was over.
