 Despite Derby's inconsistent form, Green was almost an ever-present throughout the season and was linked with moves to the Premier League with Wolverhampton Wanderers and Blackpool

In the January 2011 transfer window, Green remained at Derby and remained a key figure in the side before picking up a cruciate and mediate ligaments injury in a 4–1 defeat at Cardiff City which ruled him out for the subsequent six to nine months.As a result of his injury, Green missed the rest of the 2010–11 season and the first 16 games of the following season, returning to action in a reserve fixture against Sheffield United on 15 November 2011.He was allocated squad number 32 upon his return.
