The 27-year-old was diagnosed with a spinal contusion after being injured during his side's 62-5 English Premiership defeat at Saracens on 4 January, and underwent surgery three days later to relieve the pressure on his spinal cord caused by bruising and swelling
After four weeks in St Mary's Hospital in London - three of them in intensive care - the New Zealand-Samoan second rower has now been moved to a specialist spinal injuries clinic at the Royal Buckinghamshire Hospital in Aylesbury.
