Nottingham Forest have reportedly admitted defeat in their attempt to sign Djed Spence on a permanent basis from Middlesbrough.
Spence enjoyed a successful loan spell at the City Ground last season to help Forest secure promotion to the Premier League for the first time in 23 years with a play-off victory over Huddersfield Town.
The wing-back played a pivotal part in Steve Cooper's side, scoring three goals and five assists, and formed a dangerous partnership with Brennan Johnson on the right.
