Smith played more than 28 games for Scottish League Two side East Fife last season after making the switch from Celtic.
The 19-year-old has started in between the sticks for the Fifers this term but it’s now claimed he’s heading to the North East for a trial.
According to the Daily Record, Smith will train with United this week after East Fife gave it the green light.
Smith previously trained with Championship side Stoke City but now Newcastle want to get a good look at him.
The Magpies have made a big effort to strengthen their academy ranks this summer.
Alex Murphy arrived from Galway United to join Elliot Dickman’s under-21s squad, while Charlie McArthur has linked up with the under-18s after joining from Kilmarnock.
United also confirmed the arrival of left-back Jordan Hackett following his release from Tottenham Hotspur.
