Zac Stacy appeared in a Florida courtroom Friday morning just hours after his arrest ... and a judge told the former NFL player he would not be allowed out of jail until he surrenders his passport.
Stacy -- who went before the judge wearing a COVID mask and a blue shirt -- said that might be an issue ... revealing his passport is currently locked in his car in Tennessee.
When the judge pressed, though, Stacy and his attorney said he could have a friend access it and mail it to him -- although they said that might not happen until Saturday or Sunday .
