I accidentally did something like that, got too rough with a helmet head.
If you're willing to baby that plant along until she recovers, she might make it. That tiny true leaf she has might just save her. That's what happened with mine. It sat like that for days (can't really remember how many), then the true leaf started growing then it got a second set of one blade leaves and grew normally from there.
Good luck, you really want to watch the environment with this one, she's had a shock and more stress before she starts to grow will probably kill her, but don't give up until she's brown.
edit:I just noticed you said auto. She probably won't yield well even if she survives, but I would still try.
