Crystal Palace midfielder Jonny Williams is having a medical at Sunderland ahead of a loan move.

Williams, who has not played for the Eagles in nearly three years, has been plagued by injuries throughout his career.

He signed a new three-year deal with Palace in May, but is set to go out on loan for a seventh time.

Williams, 23, will join a Sunderland team looking for a return to the Premier League at the first attempt.

The Black Cats have had a tough start to the season, winning just once.

And in Sunderland boss Simon Grayson’s 4-4-2 formation, the Eagles academy graduate will be able to play in central midfield or out wide.
