Northern Ireland's forgotten man Will Grigg has joined Chesterfield from League Two side MK Dons for an undisclosed fee.
The former Wigan Athletic and Sunderland striker has agreed a three-year deal with the National League side.
Grigg follows the arrival of midfielder Tom Naylor from Wigan, with Chesterfield manager Paul Cook plotting a promotion challenge after missing out in the play-off final to Notts County last season.
