Blocked vein throws doubt on Chiefs hooker’s availability for the World Cup.
He is repeatedly touted as the All Blacks' third hooking option but Nathan Harris first must focus on getting back on the field.
Harris has been stuck on the sidelines since injuring his ankle on the end-of-year tour and, for the last several weeks, a return to action with the Chiefs seemed imminent.
But the 23-year-old has suffered a setback in his rehabilitation, throwing into doubt both his immediate playing fate and his status as the front-runner to join Dane Coles and Keven Mealamu at the World Cup.
Harris, having stepped up his training in anticipation of a run out this month, is now back in a moon boot after an MRI found a blocked vein in his big toe. The ailment prevented efficient blood flow to the digit and caused pain and inflammation, shutting him down for a couple of weeks.
