On Thursday night, Bolt stormed to his third 200m gold at the Olympic Games but after the race, he suggested that he may concentrate on the shorter distance in 2017.
The 29-year-old told BBC Sport: "I don't know. I said when I come to the championships in London next year it would be 100m and that's it.
"My coach has a way of trying to convince me, but personally I believe this is my last one."
Bolt will target a ninth Olympic gold medal when he runs for Jamaica in the men's 4 x 100m final.
