Michael Phelps, the 23-time Olympic gold medallist, has jokingly challenged UFC champion Conor McGregor to a swimming race.
The American swimmer posed the question on Twitter just three days after McGregor lost his multi-million pound fight against Floyd Mayweather in Las Vegas.
The Irish fighter has yet to respond to Phelps invitation but interest around a possible race has already grown with the Olympians post being re-Tweeted more than 35,000 times.
Phelps took on his own challenge this summer when he lost in a race against a computer-generated shark.
The 32-year-old lost by two seconds in a Discovery Channel publicity stunt in July.
McGregor has yet to respond to Phelps though we wouldn't hold our breath on this one...
