Prayers up for Derek Carr [Mod Edit: Derek Carr is week to week with fractured left hand and concussion]

So has there been confirmation that his hand is broken? The tweets I saw didn't actually say that it was, only that it was the concern from a source.
The alleged source came from Underhill. He didn't name the source for obvious reasons. I don't think we'll get a clear answer until whenever the injury report, or maybe from the staff in the next day or two, idk.
