Nottingham Forest have re-signed midfielder Jack Colback from Premier League side Newcastle United on a season-long loan.

The agreement also gives Forest the option of making the deal permanent at the end of the 2018-19 campaign.

Colback scored one goal in 16 appearances for the Championship club last term during a previous loan spell.

He has played 102 games for Newcastle since joining them from Sunderland in 2014, but none since May 2017.
