Notts were keen to keep Jupp for a 3rd and final month on loan, but Wimbledon requested that he returned this week.
He has now been released by Wimbledon to free up some money for the Milton Keynes bound club, as he was out of contract at the end of the season anyway.
However, Notts boss Billy Dearden was quick to deny he would be coming back to Notts.
"He has probably come to an agreement with his club to pay-off the remainder of his contract," Said Dearden.
"Whether he has got a deal lined-up with another club or not, I don't know.
"But what I do know is that we obviously do not have the money to make a signing, so if he has, it isn't us."
