He had loan spells at Southport, Burscough and Wrexham before moving to Mansfield Town in November 2010.

A further move to Altrincham in the summer of 2012 led to a loan spell at Marine, where he scored twice in 4 appearances.

A second loan took him to Kendal, and 10 goals in 11 games led to a permanent move to the Mintcakes before he joined Skelmersdale in 2014.

He signed a three-year deal with Marine in the summer of 2017 and won the players' player of the season award in 2017/18.
