Substitute Alexander Isak scored an 89th-minute winner after Aleksandar Mitrovic’s penalty for Fulham was disallowed as Newcastle returned to third in the Premier League.
Club record signing Isak, on his first league appearance since September after injury, nodded home from close range at a jubilant St James’ Park.
Mitrovic looked to have given Fulham the lead against his former team, but his spot-kick was ruled out because he accidentally kicked the ball on to his standing foot when he slipped.
It was a dramatic final 30 minutes to a tight game which Newcastle edged without being able to create clear chances.
In the end Isak, who made a promising start to life on Tyneside before his injury, was in the right place to convert strike partner Callum Wilson’s knock-back.
Fulham manager Marco Silva was booked for protesting after the final whistle, with his side unfortunate to see their five-game winning run ended. (BBC)
