Sunderland defender Michael Turner is in the process of completing a move to Norwich City, reportedly undergoing a medical at Carrow Road on Wednesday.
Turner, 28, arrived at Sunderland from Hull City in 2009 for a fee of £4 million after previous spells at Brentford and Charlton.
With the arrival of Carlos Cuellar at the Stadium of Light, joining existing centre-backs John O'Shea and Wes Brown, Turner's first-team prospects looked limited for the season to come.
Martin O'Neill is keen to trim his squad and fellow defenders Matthew Kilgallon and Titus Bramble are also believed to be surplus to requirements on Wearside.
Turner had been linked with a return to Hull, currently managed by Steve Bruce, but the former Sunderland manager came out to deny these claims.
Norwich, though, are keen to bolster their defensive options and Turner will follow Scotland international Steven Whittaker, signed from Rangers on a free transfer, in arriving in East Anglia this summer.
