The thoughts of everyone at Newcastle United are with Cheick's family, friends, teammates and everyone connected with the clubs he represented.
The Ivory Coast midfielder, who made more than 150 appearances for the Magpies between 2010 and 2017, was training with his current club, Bejiing Enterprises, on Monday when he collapsed.
He was taken to hospital but sadly passed away.
Cheick cemented his place in Newcastle folklore with his dramatic equaliser in the 4-4 draw against Arsenal in February 2011.
