The 21-year-old has linked up with the Pilgrims until January – with a number of first team players currently being sidelined through injury.
He gained considerable experience on loan at Dunfermline Athletic in the Scottish Championship last season – having also previously enjoyed a loan spell in the National League with Ebbsfleet United.
Fogarty is registered and eligible to face FC Halifax Town on Tuesday evening – having been allocated squad number 18.
