All Black Rugby Great Colin Meads, who has been in hospital for 11 days, has told RNZ he is set to receive test results tomorrow.
Sir Colin, who was first admitted to hospital last month and later released, said he was continuing to recuperate in Waikato Hospital after being readmitted with kidney pains and small blood clots.
The former lock forward said he had a scan on Friday and was expecting the results tomorrow.
He said he had been unwell for about six months but was now better.
Sir Colin, who has just turned 80, said he had a lot of messages from his old rugby comrades during his time in hospital.
He was an All Black between 1957 and 1971, and played 55 Test matches in that time.
