Thompson was handed an 18-month contract in 2011.12 after impressing during the team’s pre-season campaign.
The technically gifted midfielder made his senior debut in last season’s Johnstone’s Paint Trophy clash with local rivals Chesterfield but also featured in the landmark friendly against Juventus in Turin.
The Nottingham raised youngster later spent time on loan with Lincoln City to pick up first-team experience but was given an opportunity to shine in the County senior side at the end of the 2012.13 campaign.
Thompson made an impressive contribution off the bench in a fixture with Preston North End, before being handed his full Football League debut in a 3-1 victory over Colchester United.
