Uncured hay that freezes....what will happen?

Hello everybody....hope all is well.

I have a coastal Bermuda patch that has enough grass present to justify baling it considering our local hay prices.

Our first freeze is forecast for this coming Wednesday (forecast to drop to 29 for a couple hours). If I cut tomorrow, there is no way that this grass will be cured before that freeze arrives. My question is what will happen to this hay if it freezes before its fully cured?

Thanks,
Chris
