Leeds United chief executive Angus Kinnear has thanked football fans from around the world for the support received by 18-year-old Jack Clarke, who was taken ill during yesterday’s game with Middlesbrough.

He said: “Jack has had messages from football fans from every club you can imagine and we all really appreciate it.

“Jack spent the night under the supervision of the medical staff from the club and he will return home today.

“He will undergo some more tests this week and everything is looking well, but he won’t train for the rest of the week.

“In the meantime we would like to thank everyone who has sent well wishes and once again thank Middlesbrough Football Club for all they did for Jack.”
