Aitor Karanka is pleased with George Friend's progress as the defender recovers from a knee injury.

The Head Coach says Friend is his only fitness concern ahead of Monday's game against Hull City at the Riverside Stadium.

"As everybody expected, George is going really quick," Karanka said.

"He's the kind of player who wants to play the following day.

"But we have to keep calm. He's doing really well but I think another week or two at least."

Meanwhile, Karanka says Dani Ayala could feature Monday evening's fixture.

"Dani is training with the team and he is ready, it's just my decision," Karanka said.

"I have to take it all in and we will see."
