Peterborough United say midfielder George Boyd's proposed move to Nottingham Forest fell through because of an "inconclusive eye test".
Forest boss Alex McLeish wanted the 27-year-old former Stevenage player but Peterborough issued a club statement claiming the move collapsed because of an inconclusive vision test.
"Total disgrace, the whole thing," Posh chairman Darragh MacAnthony tweeted.
"I'm devastated for George. I got a phone call off him in bits."
He added: "George agreed terms with Forest and went there for a medical.
"He said that he passed the medical then they made him do an eye test. He's played 300 games and scored from the halfway line the other month, but Forest say he has an eyesight problem.
"The whole thing stinks. Alex McLeish wanted to sign him. It's the most ridiculous thing that's happened to me. He will be back at Peterborough."
A Forest spokesman said he was unaware of the details and was unable to comment.
