Sunderland have a recall option for Graham ahead of next month's winter market.
"At the minute it is out of my hands," he said. "I have not spoken to anyone at Sunderland, I have not spoken to the new manager, obviously it was Paulo (Di Canio) who sent me out on loan.
"At the minute I am just concentrating on doing well for Hull. As I said the manager showed a lot of faith in me in the time I have been here and I want to repay that.
"I think it is a season-long loan, but if there is an option then we will have to see what happens."
