West Ham manager Alan Curbishley claims his club have accepted a bid from Sunderland for Anton Ferdinand.
The 23-year-old defender is reportedly considering the offer, thought to involve a fee of approaching £8million.
Curbishley, whose team today lost 3-0 in the Barclays Premier League at Manchester City,said: 'The board have accepted the bid - he's not renegotiated his contract - and the decision was taken out of my hands.
'I don't know where Anton is in terms of signing for Sunderland - but once the club accept the bid it moves on.'
Ferdinand's current contract is set to end in 2010.
Curbishley, meanwhile, is hoping to sign a defender before the transfer window closes on September 1.
'We are thin on the ground,' he said.
'If we lose another defender we will have to react to that.'
