The defender was at the centre of a £25 million bid by the Irons but has now committed himself the Tyneside outfit after it looked – at least for a while – that he may be a new Hammers arrival.
With Winston Reid injured and out for three months, the Hammers instead have hung their hats on Paraguay international defender Fabian Balbuana, who could easily start the season at the back with another new arrival Issa Diop.
With Angelo Ognonna also available, and both Declan Rice and Reece Oxford showing prominently in pre season, the Hammers look okay at the back.
At Newcastle’s training camp in Dublin, Lascelles said: “I’m happy here, I’m a Newcastle player, I’m still tied down to a long contract.”
