John Carver has been reluctant to utilise the club's youngsters during his time as manager so far, but it seems he may have a change of opinion before the end of the season.
Both Armstrong and Kemen have been two of Newcastle's stand-out performers for the Magpies' development squads and Carver is thought to have been impressed by the standard of the displays they have been putting in.
If he does put either of the promising duo in it would be a major boost for supporters of the club, with questions over whether academy graduates have received enough chances at St. James' Park.
Armstrong has already made 10 appearances for Newcastle this season, but they have been fleeting showings rather than starting roles.
It seems that he is now close to displacing Emmanuel Riviere as the club's second choice striker whilst Papiss Cisse is out injured, though, and if he does he should receive plenty of game-time between now and the end of the season.
Kemen, on the other hand, is still yet to make his debut for the first-team squad, but with so many players on the treatment table he could be handed his maiden chance to impress soon.
