Having previously played for Epworth Town Colts, Harrison makes the step up to the NCEL and joins the Swans as an exciting new attacking option.
He scored seven goals in 15 appearances last season for Epworth, with their Lincs League season declared null and void. He was named man of the match twice and will surely look to continue his development with the Swans.
At just 19, Harrison is a talented young player who was in high demand. He can play in midfield or attack, yet another example of the versatility the Swans have in terms of options for the season ahead.
