Northern Ireland international Carl Winchester is expected to complete a move to League One club Sunderland.
The 27 year old has been a standout player in League Two over the last couple of seasons.
He has previously worked with Sunderland boss Lee Johnson when the pair were at Oldham Athletic.
Winchester has just one Northern Ireland senior cap, playing against Wales in the Celtic Cup in 2011.
His twin brother Jude plays in the Irish Premiership with Ballymena United.
