The heavyweight boxer was eliminated from the competition along with professional partner Natalie Lowe when viewer votes and judges' scores for their cha cha cha yesterday were combined.
The pair were joined in the bottom two by EastEnders icon Anita Dobson and her partner Robin Windsor.
Harrison had finished in the danger zone on three previous occasions, staying in the competition over Edwina Currie, Nancy Dell'Olio and Lulu.
Asked by hosts Tess Daly and Claudia Winkleman for his Strictly highlights, Harrison replied: "There have been many. I've really enjoyed myself."
He then poked fun at a well-publicised loss in the boxing ring, quipping: "Imagine the first week I was 100/1 to go out, so hopefully all those people who lost money on me with the David Haye fight, hopefully they got their money back! It's been great, I had a great time… I really enjoyed it."
Lowe added: "I just want to thank all the people at home who voted, who kept us in. It's been a great journey. Thank you!"
The final eight Strictly Come Dancing contestants will perform live from Wembley Arena for next week's show, which airs at 6.55pm on Saturday (November 19) on BBC One.
