The 20-year-old centre-back spent time on loan in the National League North with Salford City and Stalybridge Celtic and in the Evo-Stik League Premier with Trafford last season and will now be looking to make an impact in the National League on Tyneside.
The 6`2” defender is yet to make an appearance for the Huddersfield first-team, who were promoted to the Premier League via the play-offs in May, but he has been in impressive form for their under-23 side and during his loan spells.
Arriving at Huddersfield aged 11, Horsfall has progressed through the ranks at the West Yorkshire outfit and was involved in Salford`s play-off semi-fibal defeat to eventual winners FC Halifax Town.
After losing defenders Liam Hogan, Manny Smith and George Smith so far this summer, manager Neil Aspin has been keen to boost his defensive depth as Horsfall becomes the sixth out-and-out defender in the Heed squad.
The signing of Horsfall also coincides with the Tynesider`s focus on bringing in young players to help bolster the side, whose average age is just 23 going into the new season.
