Kelly progressed through the youth setup at Sheffield United before making his first team debut during a 3-1 away defeat to Coventry City in April 2016.
A loan spell to National League North side Stalybridge Celtic followed later that year and the young defender made 10 appearances during his stay at the club.
At the end of the 2016/17 season, Kelly was released by newly promoted Sheffield United and Port Vale snapped him up on an initial one-year contract.
Also capped by the Republic of Ireland's U18 and U19 sides at international level, the 19-year old arrives at Vale Park with great potential and he will be hopeful of impressing.
