Then "out of nowhere" another Melville player came up to him and punched him in the head, he said.
"I don't remember anything after that.
"I felt like I was dying. I could hear noises far away from me, people talking," he said.
The 26-year-old woke up in hospital, shocked and disoriented.
"I didn't know where I was. My sister told me what happened."
The man who hit him was a close friend of his, and he had no hard feelings.
"I'm not angry with him. His dad is a close mate of mine.
"I don't want him banned from rugby or anything like that."
Mr Filivao was discharged from hospital yesterday evening and was told by his doctor he wouldn't be able to play rugby for another four weeks as he recovers.
"I feel a little bit sore, but I'm quite happy. I was worried yesterday at the scan result.
"I was worried something happened to my head or my neck and spine, but the result came out and everything is all good."
Waikato Rugby Union operations manager Bill Heslop said the Melville player was yellow-carded during the match and a judicial process would be under way tomorrow.
"The WRU has received a citing request from the Morrinsville Rugby and Sports Club which will be followed up on Monday morning along with any other judicial requirements."
Morrinsville lost to Melville 5-50.
