The Senegal international has reported to Jack Ross' side more than two months after he was expected back for pre-season training
Papy Djilobodji has received a frosty reception from Sunderland after returning to the club.
The former Chelsea defender spent last season on loan at Ligue 1 side Dijon, but failed to report for pre-season training with Jack Ross’ side.
While Sunderland have made a strong start to life in League One – they lie fourth in the table, undefeated after six games – Djilobodji has been notable by his absence from the Wearside club’s ranks.
