Midfielder Etuhu, 25, will join Roy Keane's Sunderland for £1.5million, with a portion to be paid to his former club Preston North End as part of the terms of his £450,000 move in January 2006.
Etuhu was offered an improved deal to stay at Carrow Road, but chose the bright lights of the Premiership. He joins Manchester United's Kieran Richardson on Wearside, as wel as former Newcastle and Cardiff striker Michael Chopra.
