Newcastle booked their place in the fifth round of the FA Cup with a laboured victory over Fulham at Craven Cottage.
A controversial first-half goal from Sean Longstaff set the visitors on their way, with the midfielder sweeping a left-foot effort into the bottom right corner after the ball deflected into his path off the arm of team-mate Bruno Guimaraes.
The hosts were aggrieved by the decision, with several home players complaining to referee Jarred Gillett before the goal was confirmed by a video assistant referee check.
Dan Burn doubled Newcastle's lead just after the hour mark, lashing in from close range against his former employers when home goalkeeper Marek Rodak could only parry Sven Botman's header.
