Anthony Gordon's second-half strike was enough to see Newcastle prevail in a heated Premier league clash against Arsenal at St James' Park.
The 22-year-old fired in from close range but Magpies fans were left waiting to find out if his 64th minute effort would stand as VAR checked for a litany of potential infractions in the build-up.
The tie had burst into life in the first period after Kai Havertz received a yellow card for a late tackle on Sean Longstaff. Tempers boiled over before Bruno Guimaraes found himself fortunate to stay on the pitch after a stray elbow on Jorginho.
