Killie Check Out Toon Midfielder
Kilmarnock have taken the 21 -year-old on loan.
Killie manager Jim Jefferies: 'Martin's CV is very impressive. You don't play in the Newcastle first team if you don't have something about you.
'The opportunity to stay was there for him but he turns 22 in December and he wants first-team football.
'Newcastle are a very big club and the chances of playing when you have the likes of Duff in front of you are limited.
'The fans down there demand big-name signings and he knows that he will have to move on to realise his goals in the game.
'He's certainly worth a look and we'll do that over the next few days before having a chat on Friday to determine whether or not it's going to go any further.'
