A defender who can occupy a number of positions, Johnny signed for the Millers in the summer of 2010 from Stockport County.

Adept at playing in either full back position and at centre half, Johnny signed a two-year deal after suffering relegation with Stockport in 2010.

He started his career at Reading but it was at Kidderminster Harriers where he made his name after two successful loan spells. A move to Mansfield followed where Johnny enjoyed two years and over 80 league games for the Stags.

He moved to Stockport in 2008 and despite some notable individual performances he couldn't stop County from being relegated in 2010.

Last season he showed some of his best form deputising for the injured Ryan Cresswell at centre half and netted in the 4-2 victory over Burton, before a serious knee injury prematurely ended his campaign.
