Sunderland have confirmed the departure of academy graduate Denver Hume to League One rivals Portsmouth.
The full-back joined the Black Cats as a 10-year-old and spent 13 years on Wearside, making 82 appearances and scoring three times.
However, Hume has struggled for game-time under Lee Johnson this season, and the promise of first-team football at Fratton Park has paved the way for the 23-year-old's exit for an undisclosed fee.
