The popular custodian played some pre-season games for the Millers in 2011 but joined Arnold when it became obvious that Danny Marshall was going to retain the Number 1 jersey for the forthcoming campaign.
However, 12 months later Kearney was back and this time he made the goalkeeper's shirt his own, barely missing a game before picking up an injury in a late-season win at Market Drayton that would see him ruled out of the Notts Senior Cup final win against Sutton Town.
Last year he made nine appearances before injury once again ended his season, bringing his Carlton total to 55 games.
We wish him all the best at Greenwich Avenue.
