Born: Preston, 26th September 1995
Harrison is a central defender who joined Dale from Sheffield United in June 2016.
The 20-year-old had been with The Blades since the summer of 2014 and spent the latter part of the 2014/15 season on loan at Tranmere.
Born in Preston, Harrison started his career along the M55 at Blackpool, making his debut in April 2014 in a 1-0 home defeat to Burnley.
McGahey signed for Sheffield United for an undisclosed fee in the summer of 2014. Despite McGahey being out of contract at Bloomfield Road, his age meant that Blackpool were due a fee and as such the two clubs agreed a compensation package.
