All In Dark Almost Worked

Down to about 12,000 chips in the @PeppermillPoker Main Event Day 1A, Billy Casey announces all-in-dark on the final hand before late registration ended.
The player to Casey's right moves all in and turns over AJ, Casey looks down and to his surprise is holding 77.
The board runs out 2-3-5-4-T and Casey's pair runs into a turned Broadway and he's lost his 3rd bullet of the day.
Fear not, he'll fire again tomorrow .. wait, he bought back in now for his 4th bullet...
