Britain's two-time Olympic gold medallist Helen Glover says it is "highly unlikely" she will compete at the 2020 Games in Tokyo - but she is yet to decide on her long-term future.
Glover won pairs gold at the 2012 and 2016 Games alongside Heather Stanning, who retired in November 2016.
"I'm still training but whether I have the drive... I don't know whether it's what I want right now," she said.
Speaking on BBC Radio 5 live's Friday Sports Panel, she added: "I haven't absolutely said no but I think it's highly unlikely.
"I think right now I wouldn't feel like I was sat on the start line in a place where I had given it everything."
Glover, who gave birth to her first child four and a half months ago, said there was always a temptation to compete in Tokyo in two years' time.
"I still like this sort of craving to do something physical. Whether it's the next Olympics, I don't know," Glover added.
"My long-term future is still undecided. I still have unfinished business in some way, I feel."
