Nyron Nosworthy has completed his move to Sheffield United on loan from Sunderland.
Skysports.com understands that Portsmouth failed to agree a financial package with the former Gillingham defender, so he opted for Bramall Lane instead.
Sunderland boss Steve Bruce is a fan of Nosworthy but, with the recent signing of Matt Kilgallon from the Blades and the imminent arrival of Alan Hutton, he agreed to a loan for the 29-year-old stopper.
Nosworthy attracted interest from a number of clubs and Pompey were favourites, but they could not agree terms.
Now Sheffield United have finalised a deal for Nosworthy, who will spend the rest of the season with the Championship club.
