A club record £1.5m bid by Preston for US international striker Taylor Twellman has been rejected by the MLS.
North End offered $3m (approximately £1.5m) to Major League Soccer for Twellman, plus a further sell on clause but this was turned down.
PNE chairman Derek Shaw told the club's website: "Unlike the situation over here, it appears the MLS do not want to negotiate, they just say 'yes' or 'no'.
"It's disappointing because the lad is very keen to join us, but it appears the opportunity is not going to be there for him during the transfer window."
