Martin Nel said last week that he was scrapping the raffle in which he hoped to sell 100 raffle tickets for USD 1,500 each in Las Vegas next month.
Nel says the raffle winner could also have chosen to have a lion collared for research, and that the project was designed to raise funds for conservation studies at Zimbabwe's Bubye Valley Conservancy.
Some conservationists describe lion hunting as a threat to the species, whose numbers in the wild are dwindling.
