Kenny joined Keith Hill's side in the summer of 2009 as Dale searched for a new number one goalkeeper following the release of Sam Russell and James Spencer.

Kenny began his career Partick Thistle and made a total of 290 appearances in his 10 years there. During his time there he was named in the Scotland squad twice under Berti Vogts but failed to make an appearance. He joined near neighbours Accrington Stanley in 2007, but suffered a broken leg in October of that year in a match at Bradford. He returned the following February and continued to impress. He was again an integral part of the Stanley side the following year that survived relegation from the Football League. He made 71 appearances in his time at the Crown Ground.

He made the switch to Spotland in the summer and has impressed with his fine reflex saves and the willingness to come off his line.
