The Kiwi heavyweight fighter is set to face British boxer Whyte next month on July 28 at the O2 Arena.
I think I sacrificed my boxing entertainment, that risk-it-all mindset I had- British boxing champ Anthony Joshua
Anthony Joshua defeated Parker by unanimous decision at Cardiff's Principality Stadium earlier this month.
"When people were telling me, 'Parker is quick you know, he can fight,' I was thinking, 'He can, I'm going to get banged out in this fight'," he said.
Parker's trainer says it won't be long until Parker is back at the top of the heavyweight division.
The village of Fale’ula, where his mother is from, were in high spirits on the day of the match.
Parker found an opening early in the sixth round but he was cut off by the third man in the ring.
Parker and Barry said their attempts to understand Giuseppe Quartarone's ruling on fighting inside was lost in translation.
Team Parker also praised Anthony Joshua after this morning's 12 round slog-fest.
