Danny Graham has returned to England from Sunderland's pre-season training camp in Italy.
The former Swansea City striker is not believed to be injured but has been sent home by manager Paolo Di Canio.
Sky Sports suggests that Graham, who arrived at the Stadium of Light in January, does not have much of a future on Wearside following the summer arrival of Jozy Altidore from AZ Alkmaar.
