From there, Lonergan spent three seasons at the University of Bolton Stadium.
Injuries restricted his impact to begin with, but he hit his stride in the 2014/15 season with 32 games under his belt for the Whites.
Murphy played in over 160 games for the Cheshire based outfit before joining Leeds United in 2013 for a fee believed to be over £1million.
