Scunthorpe midfielder Matt Sparrow is set to join Brighton after rejecting the Lincolnshire club's latest contract offer.
The 28-year-old is poised to end his 11-year stay at Glandford Park, with the Seagulls set to bring him in as a replacement for former captain Andy Crofts, who has moved to Norwich.
Sparrow becomes the second player to depart the club to make a step down from the Championship to League One after Grant McCann moved to Peterborough in May.
Albion boss Guy Poyet was thought to have lined up David Prutton to fill the role left by Crofts, but his subsequent move to Swindon has left the Uruguayan to select Sparrow as his number one option.
Andy Crosby, assistant coach at Iron, insisted that he did not want to see the player leave.
However, Crosby conceded that Scunthorpe could not stop Sparrow from going and that Brighton were signing a good player.
"He has been a great servant for Scunthorpe and he is a good lad. We obviously didn't want him to go but he has decided for whatever reason to seek pastures new," said Crosby.
"If he does go to Brighton he will do really well at that level."
Sparrow is one of three new players expected to be unveiled at the Withdean Stadium, where Poyet is hoping to turn the team from strugglers to promotion candidates.
