Evo Player Disappeared from Account

I have spent the better part of a few months painstakingly working on a Kyle Hudlin evo only for me to log on today to discover that despite him being in my active squad as recently as yesterday, this afternoon he was nowhere to be found. I'm guessing he's gone for good (the only thing I can think of is if he got sucked into an SBC--still, I would've expected a notification about submitting an active squad player) but on the off chance there's some way to recover him, I figured I'd ask. I have listed his exact stats below.
