Charlton Athletic have signed midfielder George Dobson after he left League One rivals Sunderland.
The 23-year-old, who has left the Black Cats by mutual consent despite having a year left on his contract, has signed a two-year deal at The Valley.
Dobson moved to Sunderland from Walsall for an undisclosed fee in July 2019 and played 47 times for the club.
He spent the second half of last season on loan at fellow League One side AFC Wimbledon, making 24 appearances.
He is the Addicks' third new signing of the summer after striker Jayden Stockley and goalkeeper Craig MacGillivray.
