The 20-year-old has previously represented Leeds at youth level and has since captained Matlock Town in the Northern Premier Division.
Phillipson will compete for a spot in manager Jas Colliver’s side this season, having gained more experience since his NPL debut in 2016.
On the addition of Phillipson to the squad, Colliver said “When good players come available you have to get them in,
“I’ve worked hard to get this one over the line but we feel we are the best place to provide an opportunity for Alex to express himself and gain more experience at this level.
“He isn’t ready for 90 minutes just yet as his international clearance has taken time to be processed but now we are all ready to go.
"I'm excited to see another young prospect join us”. He added.
The versatile defender will be available for selection ahead of the Sheepicorns’ trip to the Apec Taxis Stadium against Runcorn Linnets.
