18-year-old Livermore who is on loan from Premiership side Spurs sustained the injury against Wrexham in the 0-0 draw after a bad tackle from Kyle Critchell.
The player could not have an x-ray last night due to swelling around his leg and ankle, so x-ray was performed this morning and gave Steve Holland his worst case scenario with the player now ruled out until October.
Livermore has now returned back to his parent club Tottenham where he will recieve treatment for the fracture.
