Jack Colback

The midfielder is understood to be in talks with Championship club Nottingham Forest, now managed by Aitor Karanka.

It is unclear if the discussions are over a loan or a permanent move.

The 28-year-old has been training at Newcastle's Academy since last summer after being told by Rafa Benitez he was not in his plans.

Colback, signed on a free transfer in 2014 after his Sunderland contract expired, has played a handful of games for United's Under-23 side this season.
